Hi Everyone-
I have a 3300 for a pretty big client that switched to SIP from the local ILEC about a year back.
We're now noticing after adding MOH and setting up some new ACD paths that when an incoming call hits a multi-level
auto attendant the calling party hears the AA greeting and when they make a selection that takes them to an ACD path
they just hear silence. If you make the same call internally, you hear a half ring then a RAD followed by music until
the RAD repeats.
On the SIP Peer SDP page we had "Avoid Signaling Hold to the Peer" set to yes since the SIP cutover, so that isn't the fix
as I've seen in a lot of threads on this issue.
I did a TCPDUMP and looked through it in wireshark and nothing is sticking out to me.
Anyone have any ideas? I'm trying with Mitel and the carrier but don't have high hopes for anything but finger pointing from either of them.
