Hello,
I am running into an issue where trying to transfer an off-net call leg to another off-net call leg fails. The call is not terminate but remains up on the CUBE gateway.
It seems as if somewhere after I press the transfer button that the SDP starts showing 0.0.0.0 for the address.
If on the SIP trunk to the CUBE I check MTP required it works but I need to try to avoid the forcing of an MTP for all calls through the CUBE.
Here is the last SDP that is displayed:
v=0
o=CiscoSystemsSIP-GW-UserAgent 3031 6835 IN IP4 10.66.122.141
s=SIP Call
c=IN IP4 0.0.0.0
t=0 0
m=audio 17024 RTP/AVP 0 101
c=IN IP4 0.0.0.0
a=sendrecv
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15

a=sendrecv
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15
... and the call leg status looks like this:
G<id> L<id> Elog A/O FAX T<sec> Codec type Peer Address IP R<ip>:<udp>
G1284 L 4F N ANS T57 g711ulaw VOIP P5555555555 0.0.0.0:24542

G128B L 54 N ORG T15 g711ulaw VOIP P7777777777 66.2.202.134:17482
I've seen this over a year ago with another deployment but I was not invovled with the resolution. All I do recall is the resolution did not involve checking MTP required.
Thanks for the help in advance
