Incoming calls issue in Third Party SIP Phone

Hi,

Yesterday I configured my third party sip phone which is yealink in this case on cucm and successfully registered it with cucm, despite of registration i have some calling issue in this phone. I am able to make outbound calls from this phone to any other phone however issue is related to inbound calls.I tried calling its DN from anywhere but call disconnect after sometime. Also didnt get any proper sip session trace in RTMT. Kindly suggest some step to sortout this issue.

Thanks

Incoming calls issue in Third Party SIP Phone

Does the call actually get set up with audio both ways? How much time does it take before the call is disconnected? Can you capture detailed callmanager traces for a test call

Dear Manish,

Call normally dicsonnected after 30-40 sec with termination code 102 in session trace. PFB SDI  trace with 5030 is Thirdparty sip phone and 5033 is c7945. Looking forward for your suggestion.

Re: Incoming calls issue in Third Party SIP Phone

Finally a Solution to this issue.

 

Noticed that the Alert-Info Header is causing the problem, part of the INVITE message being sent out to AVAYA Phone (Third Party SIP device in my case).

 

Alert-Info: <file://Bellcore-dr1/>

 

1. Configured a SIP Normalization Script to remove the Alert-Info Header from the INVITE message.

2. Applied the Normalization script to a SIP Profile.

3. Applied the SIP Profile to the Avaya Phone.

4. Test calls were successful both-sided with proper 2-way audio communication.Script.JPG
