SIP Proxy Altering SIP Call ID - Prepending ADTN-FAILOVER

Jump to solution

We have a situation were inbound calls through an Adtran NetVanta 6355 using SIP Proxy are failing to Polycom SoundPoint IP phones.  The NetVanta SIP Proxy is changing the SIP Call-ID by prepending "ADTN-FAILOVER", which is a new call id and not recognized by the SBC.

Re: SIP Proxy Altering SIP Call ID - Prepending ADTN-FAILOVER

Jump to solution

Btilson,

I wanted to update this ticket with what was found after calling Technical Support on this issue.  This issue was caused by a software bug that was resolved in A4.10.00 and A5.03.00.  The issues stems from not having a valid default route in the unit.  Your options were to enter a default route that points out an active and "up" interface, or upgrade the firmware version on the unit.

I'm going to go ahead and mark this thread as "assumed answered", but feel free to post any additional questions you may have.

Thanks!

David

Note the SIP Call-ID is changed by the SIP Proxy:

BEFORE SIP Proxy

-------------------------------

15:02:35.250 SIP.STACK MSG         Call-ID: BC81E1A7@[Softswitch Private IP]

AFTER SIP Proxy

------------------------------

15:02:35.259 SIP.STACK MSG         Call-ID: ADTN-FAILOVER-BC81E1A7@[Softswitch Private IP]

Hello and thank you for posting to our forum.

It may be easier to work this through a regular Technical Support ticket.  Please create a support ticket from the support link on our website or call us at 888-423-8726 to open a ticket.  We will need to see your complete configuration and the following debug commands, all run at the same time, for a given test call.

debug sip stack messages

debug sip proxy routing

debug sip proxy database

debug voice verbose

Once we have found the problem, we can post it on the forum.

Regards,

Geoff
