[cisco-voip] one way audio after SIP cupover

[Haas, Neal]

Do you have WAN or dedicated fiber (Campus), sometimes it could be your internal network causing the issues. If you can do a packet trace on the port effected.

Thank You,

Neal Haas

I'd try to set up a span of the internal and external interfaces of the CUBE and have that running at all times.  Then you can see if you're receiving the packets from the carrier or not when this happens.

I get that this is usually routing but, is it also routing when the issue is intermittent?

our call flow is like so

CentLink(Provider) ----siptrunk30Meg-PPP(IQ-private)---Cube---CUCM10.5, uccx,unity

bonus facts, I have an operator who is in one of the two most affected buildings and she can recover the call after hold, resume,hold,resume sequence. then full rtp stream is there and she can hear and speak with caller.

are there SIP state change timers I can adjust, I want to tread lightly though because out of all of our outreachs seperated by a metro ethernet hub and spoke topology and almost 30 buildings here on main campus only 2 seem to be affected.
