LAN to LAN calls

Jump to solution

I have a TA908e and a PoE switch. I am able to make calls in/out (Polycom phones). When I unplug the WAN connection I am unable to make extension to extension calls. I guess my question is why the ext2ext calls won't complete. What additional setting are needed in the TA908e. Thank you in advance.

Re: LAN to LAN calls

Jump to solution

Meyerj66,

Thanks for getting us your configuration.  Does your unit show SIP proxy users when you issue the "show sip proxy user" command?  If not, we may not be configured for the correct SIP proxy mode.  Below are the mode descriptions and the corresponding SIP proxy configuration.  The configuration samples omit basic interface, firewall settings, etc. for the sake of brevity.  More complete examples can be found in Configuring SIP Proxy in AOS.

Transparent Proxy Mode

The Transparent Proxy mode is best for new installations when the phone does not need to be aware of the

device presence (transparency). In this mode, the softswitch is configured as the server and the registrar

(and Outbound Proxy when required). The phones are not aware of the AOS device, and phones are not

required to use the same softswitch. Requests sent from the phones are routed to the destination IP address

of the softswitch, and the AOS device does not require configuration to be aware of the softswitch. In

Transparent Proxy mode, the softswitch address configured in the phone is the external softswitch, and SIP

signaling is sent to the Layer 3 destination address of the external softswitch.

Transparent Proxy Mode Basic Configuration

ip sip

ip sip proxy

ip sip proxy transparent

Stateful Proxy Mode

The Stateful Proxy mode is best suited for existing installations due to the ease of converting from B2BUA

to IP phones without modifying the phone configurations. In this mode, phones or user agents (UAs) rely

on the SIP server to act as the proxy, and the configuration is very similar to the existing B2BUA. The

AOS product takes on the role of proxy. The UA is not aware of other SIP servers on the network in this

mode. Each phone is configured to register to the proxy, and the phone is not aware of the softswitch(es).

Either the softswitch(es) host name(s) or IP address(es) must be programmed in the system, enabling

communication between the two. All phones must use the same softswitch or set of softswitches, and the

phone must send all requests to the destination IP address of the AOS device. In Stateful Proxy mode, the

softswitch address configured in the phone is the proxy (AOS device), and SIP signaling is sent to the

Layer 3 destination address of the proxy (AOS device).

Stateful Proxy Mode Basic Configuration

ip sip

ip sip proxy

ip sip proxy sip-server primary <IP Address>

Outbound Proxy Mode

In the Outbound Proxy mode, the ADTRAN device’s duties may include numerous functions, such as

establishing the service provider's boundaries, receiving and sending Voice over Internet Protocol (VoIP)

traffic behind a firewall, controlling network call routing, and network quality of service (QoS). The

system may not require configuration to be aware of the softswitch. The softswitch (which can be B2BUA

or Stateful Proxy) takes on the role as the server and registrar in this mode. Requests sent from the phones

are routed to the destination IP address of the softswitch. The lack of configuration is usually not an issue

because the SIP messages contain the necessary routing information. The softswitch address configured in

the phone is the external softswitch, and SIP signaling is sent to the Layer 3 destination address of the

proxy.

Outbound Proxy Mode Basic Configuration

ip sip

ip sip proxy

Your configuration most closely matches Outbound Proxy mode.  However, this is used rarely and requires that phone insert the softswitch IP address in the SIP message headers, but that the layer 3 destination IP address be the Adtran unit.  If the output of "show sip proxy user" has an entry for each of your phones and you feel confident you are configured for the proper mode, we will likely need you to open a regular Technical Support ticket by calling 888-423-8726 or sending an email to support@adtran.com so that we can troubleshoot directly on the unit. 

Thanks!

David

Meyerj66,

Thanks for posting.  Are you setup using the Polycom phones in a B2BUA mode (one voice user per phone) or in SIP proxy mode?  In either case, we should be able to fail over, but it will change the debug commands we sue.  We will likely need to see your configuration and the output of the following debug commands for a test call.

debug sip stack message

debug voice verbose

debug sip proxy verbose

Please make sure that your configuration and debug output file do not contain any sensitive information such as IP addresses or phone numbers that you do not want to make public.  You might be able to use a find/replace to get those items of your files.  Otherwise, we will need you to create a regular support ticket by calling 888-423-8726 or emailing support@adtran.com with those files and an explanation of the problem.

Thanks!

If you dont want to encrypt your password use the following:

enable password password

username "admin" password "password"

As for decrypting a password I don't think the Adtran does that.

Re: LAN to LAN calls

yahya,

Thanks for posting!  Since the encryption is a one-way hash, it really is not possible to decrypt it within the Adtran.  You will need to overwrite and/or shut off the feature.  To overwrite, you will just need to enter your password commands again with the password you choose.  To turn off the feature, you will need to enter "no service password-encryption" and then reenter each password.  Below is an example.

TA900#conf t

TA900(config)#no service password-encryption

TA900(config)#enable password adtran

TA900(config)#username admin password adtran

etc.

Thanks!

David
