How to Configure the Cisco 7940G IP Phone for Standalone SIP?

How to configure the Cisco 7940G IP Phone for Standalone SIP? It’s a common problem while using the Cisco ip phone 7900 series. Now here we will share an example and case that the user of Cisco 7940g phone has got…

And the discussion is likes this:

The Problem: “I have a Cisco 7940g IP telephone.

I do not have a PBX. This is simply an IP phone plugged into a my LAN.

I just signed up Digium cloud SIP service.

Is there a way to make this work?

P.S. I tried entering the credentials that Digium sent me into the "5.  SIP Configuration" menu under "SETTINGS" on the phone, but I still have an 'X' over my line on the home screen.”

Someone answered: “Digium is a very-well known company because of a VoIP product called Asterisk.

Will the phone work, of course?  You have a choice of running SIP or Cisco-proprietary SCCP.  

We'll need to do a top-to-bottom troubleshooting and configuration.  Firstly, what protocol are you planning to use (SIP or SCCP) and what configuration settings does Digium require you to do from your side?”

In fact the user wants to run SIP.  He does not have any PBX or other Cisco phone hardware outside of this 7940g phone sitting on desk.

He has factory-reset the phone, and entered the credentials Digium gave him.

Settings > 4. SIP Configuration > 1. Line 1 Settings:

1. Name = (the user’s assigned Digium phone number)

2. Shortname= (his name)

3. Authentication Name=56605ed547a8437d872f6b516df6a4bc

4. Authentication Password = (another random string of characters just like the previous field)

5. Display Name = UNPROVISIONED

6. Proxy Address = sip.digiumcloud.com

7. Proxy Port = 5060

And he have confirmed with our sysadmin that the network's router is set to (1) disable "SIP helper", and (2) allow communication on specific UDP port ranges, both per Digium's knowledgebase.

…Those configuration are not enough.  

Ask Digium if NAT & ALG are supported. 

What transport protocol does Digium support:  TCP or UDP

What codec is allowed?

The Cisco IP Phone 79X5 family of phones behave differently.  It's not like the IP Phone 79X0 where the configurations are simple.  You'll need to upload the complete set of configurations to the phone using DHCP Option 150 and a TFTP server.

…Any more suggestions? Share with us…

What You Should Know about the Cisco Mobility Express Solution

Briefly, the Cisco Mobility Express wireless network solution provides a virtual wireless LAN controller functionality bundled into, currently, the Cisco Aironet 1850 and 1830 series access points. This functionality provides a simplified WiFi architecture with enterprise-level WLAN capability to small and medium deployments.

In the Cisco Mobility Express wireless network solution, one access point (AP), running the Cisco Mobility Express wireless controller, is designated as the master AP. Other access points, referred to as subordinate APs, associate to this master AP.

The master AP operates as a wireless LAN controller, to manage and control the subordinate APs, and also operates as an access point to serve clients. The subordinate APs behave as normal lightweight access points to serve clients.

For the list of supported access points, see Supported Cisco Aironet Access Points.

The Mobility Express solution provides most features of a wireless LAN controller and has the capability to interface with the following:

Cisco Prime Infrastructure—for simplified network management and managing the AP group.

Cisco Identity Services Engine—for advanced policy enforcement.

Cisco Mobility Services Engine—for providing presence level data as well as advanced spectrum solution.

Supported Cisco Aironet Access Points

In this release of Mobility Express, the following APs are supported.

APs supported as masters (support integrated wireless controller capability)	APs supported as subordinates

How to Start a Cisco ASA 5500-X Series?

If you are new users of Cisco ASA 5500-X Series Next-Generation Firewalls, are you familiar with the ASA 5500-X Series configuration? There are different Cisco ASA CX models available in a wide range of sizes, for small offices, branch locations, and Internet-edge deployments. 

In this article, we will share the simple start guide of Cisco ASA 5500-X Series, including the model ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, and ASA 5555-X.

First of all, let’s check the main package contents of ASA 5512-X, ASA 5515-X, or ASA 5525-X, ASA 5545-X and ASA 5555-X.

ASA 5512-X, ASA 5515-X, or ASA 5525-X

ASA 5545-X and ASA 5555-X

Note: The contents are subject to change, and your exact contents might contain additional or fewer items.

Power on the ASA

1. Attach the power cable to the ASA and connect it to an electrical outlet.

The power turns on automatically when you plug in the power cable; do not press the power button on the front panel. (For older models, the power does not turn on automatically; check the hardware installation guide for more information).

2. Check the Power LED on the front of the ASA; if it is solid green, the device is powered on.

3. Check the Status LED on the front of the ASA; after it is solid green, the system has passed power-on diagnostics.

Modify the Initial Configuration for the Software Module (Optional)

The ASA ships with a default configuration that enables Adaptive Security Device Manager (ASDM) connectivity to the Management 0/0 interface. When you use a software module such as the ASA FirePOWER module, we recommend that you do not use the default configuration, which can preclude the module from reaching the Internet for updates. This section describes how to apply a new configuration so the module can access the Internet. This configuration also enables a basic usable configuration for an inside and outside network.

The following figure shows the suggested network deployment for the ASA 5500-X with a software module:

Note: If you have an inside router instead of a switch, you can skip this section and instead configure the ASA to route between management and an inside network. In this case, configure the ASA and the module Management 0/0 IP addresses to be on the same network. Be sure to configure appropriate routes on the ASA and on the module so the management network can reach the inside network, and vice versa.

This procedure lets you connect to the ASA console port and paste in a new configuration that configures the following behavior:

• inside --> outside traffic flow
• outside IP address from DHCP
• DHCP for clients on inside
• Management 0/0 interface is Up, but otherwise unconfigured. The software module can then use this interface to access the ASA inside network and use the inside interface as the gateway to the Internet.
• ASDM access on the inside interface

To achieve the above configuration, perform the following steps.

1. Connect your computer to the ASA console port with the supplied console cable. You might need to use a third party serial-to-USB cable to make the connection.

2. Launch a terminal emulator and connect to the ASA.

3. Press the Enter key to see the following prompt:

ciscoasa>

4. Access privileged EXEC mode:

enable

The following prompt appears:

Password:

5. Press Enter. By default, the password is blank.

6. Access global configuration mode:

configure terminal

7. Clear the configuration:

clear configure all

8. Copy and paste the following configuration at the prompt:

interface gigabitethernet0/0

nameif outside

ip address dhcp setroute

no shutdown

interface gigabitethernet0/1

nameif inside

ip address 192.168.1.1 255.255.255.0

dhcpd address 192.168.1.5-192.168.1.254 inside

dhcpd auto_config outside

dhcpd enable inside

logging asdm informational

9. Save the new configuration:

write memory

10. Cable the inside GigabitEthernet 0/1 interface, Management 0/0 interface, and your computer to a Layer 2 Ethernet switch.

11. Connect the outside GigabitEthernet 0/0 interface to your upstream router or WAN device.

12. For software module configuration, see the ASA FirePOWER quick start guide, ASA CX quick start guide, or IPS quick start guide. Use the following network settings for the module:

–Management interface: 192.168.1.2

–Management subnet mask: 255.255.255.0

–Gateway IP: 192.168.1.1

4. Launch ASDM

Using ASDM, you can use wizards to configure basic and advanced features. ASDM is a graphical user interface that allows you to manage the ASA using a web browser. See the ASDM release notes on Cisco.com for the requirements to run ASDM.

How to…

1. On the computer connected to the ASA, launch a web browser. If you are using the default configuration and did not use 3. Modify the Initial Configuration for the Software Module (Optional), you need to connect the computer to the Management 0/0 interface.

2. In the Address field, enter the following URL: https://192.168.1.1/admin. The Cisco ASDM web page appears.

3. Click one of the available options: Install ASDM Launcher, Run ASDM, or Run Startup Wizard.

4. Follow the onscreen instructions to launch ASDM according to the option you chose. The Cisco 

ASDM-IDM Launcher appears.

5. Leave the username and password fields empty, and click OK. The main ASDM window appears.

802.11ac Wave 2, Ready for It?

802.11AC Wave 2, the next phase of Wi-Fi, brings wireless speeds of up to almost 7 Gigs. Wave 2 also brings multi-user MIMO to Wi-Fi, enabling dedicated bandwidth to be allocated to users. 802.11AC Wave 2 will allow businesses to create new ways of working, such as being able to do medical imaging over tablets or streaming videos to mobile devices in school systems.

802.11ac Wave 1 vs. 802.11ac Wave 2

Having wireless speeds that are that fast, though, does have some big implications on the wired network. If the air speed is anything greater than a Gig and the backhaul connection from the AP to the access switch is a Gig, then there’s an obvious problem, as the wired network becomes a choke point. Also, the Wave 2 solutions will require PoE+ (30W), and many businesses only have PoE (15W) in the access edge now. Also, with today’s switches, Cat5E has a limit of 1 Gig for speed.

Cisco founded the NBASE-T Alliance in October 2014 to promote solutions for more speed over installed Category 5e and 6 cables. Now we are introducing innovations that include NBASE-T technology and more across the entire breadth of our Cisco Catalyst portfolio–from compact switches to the backbone. These new innovations directly address the challenges we learned from customers.

Cisco Catalyst Multigigabit Technology can prepare your access switches for future innovations by delivering speeds beyond 1 Gigabit on existing Category 5e cables. This technology also supports Power over Ethernet (PoE), PoE+, and Cisco Universal PoE (UPOE) so you don’t need to install new electrical circuits to power your access points.

And, Cisco Catalyst Multigigabit Technology can protect your investments in existing Cisco Catalyst switches. For example, new Cisco Catalyst 3850 Mutigigabit models can be stacked with existing 1-Gb copper and fiber models. Cisco Catalyst Mutigigabit Technology is available on Cisco Catalyst 4500E, 3850, and 3560-CX switches. Use our new innovations to take advantage of 802.11ac Wave 2 capacity increases and start delivering even better user experiences.

New Cisco Catalyst 3560-CX and 2960-CX Compact Switches can help you increase speeds and agility, and lower costs. These switches offer Catalyst Instant Access mode, which means no more individual switch configuration. And they are flexible to support numerous networking environments and industries, including hospitality, transportation, retail, and others.

Two Times More 10-Gb Density for a Faster Backbone

Extend your existing backbone investments into the future. New, 32-port 10-Gb line cards on Cisco Catalyst 6800 and 6500-E Series Switches help you make the transition from 1 Gigabit to 10 Gigabits, and allow for twice the 10-Gb density. They also provide rich network services that you have come to expect from these platforms. And flexibility is built in so you can convert to 40-Gigabit speeds in future.
