Hi, we have a problem with early media.
We changed the connection between cucm and gateway from H323 to SIP.
Now the customer tells us, that there is a PSTN number which played an announcement about the costs of this call. This worked with H323.
SInce we changed it to SIP, we dont get this announcemen.
To be honest, i really dont know much about early media.
Attached you see the isdn q931 debug.
As is understand, this:
Progress Ind i = 0x8488 - In-band info or appropriate now available
should indicate, that there is early media available.
Is this correct?
If there is early media, i dont know how to transfer this information via SIP to CUCM.
Does anybody know how to solve this?
Best Regards
Daniel
