[cisco-voip] CUCM 6.1 and SIP

[Eric Pedersen]

What are your SIP devices?

 

I believe whether an MTP is allocated depends on how the SIP device
handles DTMF.  If it can do KPML for out-of-band DTMF passing then CM
won't have to allocate an MTP.  I was able to get this working with a
SIP trunk to a CME router.

I'm attempting to make calls between SIP and SCCP based devices.  

 

What I'm seeing in my traces is that ALL audio goes through the CUCM
server and not direct RTP between devices like I would have expected.

 

I do not have ANY MTP resources assigned to these devices, and DTMF
intercept is off (for now).

 

Has anyone run into this before?
