Hello
I am currently setting up a CME with a SIP Tunk for calls to a remote destination (external numbers).
Calls between CME and external numbers work OK, but if I attempt to put a call on hold or to transfer it, that call ends abruptly.
In a CM scenario, I would force the SIP Trunk to use MTP, but in CME I don't find a way to force SIP Phones to use MTP (there is a mtp command for ephones though).
Is it possible to force mtp on a SIP Phone in CME?
Is there any other possible cause for the failure of Call on Hold and Call Transfer?
I would appreciate any help with this.

Hello
thank you very much for your help
the trace of the call indicates codec negotiation g279
What codec is negotiated for the call ?
g729
What codecs does your ITSP support ?
g729
What codec is your MOH file ?

I have the same problem, so could you solve this issue?

Hi,
Have you tried contacting ITSP (your provider) about this error? Generally, ITSP expects "Early offer (SDP in in initial invite) but in your case SDP is also there in your 1st Invite.
Regards...
Ashok.

Codec should not be a problem because the ITSP accepted the initial INVITE with g729.
The ITSP may be disconnecting the call because of the a=sendonly attribute in the INVITE sent to them when pressing Transfer.
Try adding this command on the router.
voice service voip
sip
midcall-signaling block
This will block the INVITE for sendonly being sent to the ITSP. The ITSP leg will always remain connected and not change states.
