We configuring an IVR system with a third party. This third party cannot connect the audio streams after transferring call (not a true transfer just trying to tie 2 trunks together on their end). They are telling us to troubleshoot further that there should be SDP sent in 183 from CUCM. Right now it is:
IVR <--> CUCM
> INVITE SDP
< 100 Trying
< 180 Ringing
< 200 OK SDP
They are telling us they need SDP sent before the 200 OK on either 180/183.
