Re: SIP trunk Issues

Tasneem Fazal · ‎09-29-2019

Hi All,

I am having issues in setting up SIP trunk with Service Provider, we are not receiving any calls (no Invite) and neither make any outbound calls, looks like its some interoperability issue with telco which we are not been able to sort out. when I enable "debug ccsip messages". I am continuously receiving debug messages below, I am not sure if its asking me to enable anything on my side more specifically?

Thanks Deepak for looking into this.
I didn't configure all the dial peers, just configured a few first testing. ISP told us to configure SIP option messages, what that mean? here is the config by the way.

Hi Tasneem,

Options ping enables checking the SIP trunk status by sending heartbeats at regular intervals to the provider IP address. I have given a sample config below for your reference.

You need to configure a voice class profile for keepalives as below:

voice class sip-options-keepalive 1
description UDP Options consolidation
down-interval 49
up-interval 180
retry 7
transport udp

Apply this to all dial-peers pointing to provider SIP trunks. For example dial-peer 10 as below:

dial-peer voice 10 voip
voice-class sip options-keepalive profile 1

Thanks Rajan,
under dial-peer 10, I configured keepalive and option ping. Is that not sufficient?
moreover when when I enable "debug ccsip messages" , I am constantly receiving below messages which I am not sure indicate any underlying problem.

That should be fine but you should also this gateway/CUBE responding to those OPTIONS message from provider. Is that happening ?

Tasneem Fazal · ‎09-30-2019

Hi Rajan,
That is also my concern , i am not sure what should I enable to reply to those option messages. please advise?
