Is it possible to configure a SIP trunk on CUCM to bypass the CUCM for media traffic? I have a SIP trunk between CUCM and FreePBX server. Phones register to CUCM and calls route out to SIP trunk to FreePBX. I want that once the call is setup the rtp traffic flows between the phones and the voice provider on the internet, bypassing CUCM and FreePBX servers. I looked online but could not find any way to configure CUCM to bypass itself for media traffic. Is this possible to do and how?
There is no such option in SIP trunk configuration that you are looking for. By default CUCM is a signalling device which means RTP would not flow through CUCM server. exceptions are below.
MTP being invoked because of below
MOH server being allocated on CUCM.
Software conference bridge being allocated.
If non of the above is the case then RTP would always be between endpoints independent of CUCM.

Thanks for the quick response. I do not have any requirements that you listed. So, I am not sure why the RTP is still flowing through CUCM. The setup is as follows:
Phone-->CUCM --[SIP trunk] --FreePBX-- [SIP Trunk] --Voice provider.
And the RTP flows as below in either direction (not same both ways):
Phone --> CUCM-->Voice Provider
Voice Provider -->FreePBX-->CUCM-->Phone
Do you have any idea why?
