[cisco-voip] Odd call behavior CME,CUBE,CUCM

[Ryan Huff]

HA! Thanks Brian ... orphaned passthru .... this was the 28th (seriously) time I reviewed the config ... finally spotted it.

Is this because CUBE is presenting DTMF as part of the INVITE?

Thanks,

Ryan

I have CME that has a SIP phone registered to it and a SCCP phone registered to it.
SIP=4002
SCCP=4001
 
I have a call path that looks like:
 
CUCM->SIPTrunk->CUBE->SIPTrunk->CME
 
When I dial the SIP phone (on CME) from call manager the call completes and goes fine. When I dial the skinny phone (on CME) from call manager the call immediately fails. However, from CME, using the skinny phone, I can dial anything in call manager and the call completes.
 
CCSIP on CME (for one of the failed calls) shows the INVITE then TRYING then SIP/2.0 500 Internal Server Error. CCAPI INOUT shows a cause code of 16, but this was anything but a normal clearing. Just for the hell of it, I also added a transcoder in CME and registered it in telephony-service, just to see if there was a codec flying around that I wasn't seeing .... but alas, no.
 
I've attached the ccsip and ccapi inout; I think I have just been starring at it too long ... I can't see it.

Thanks,

Ryan
