Hi all,

I'm seeing a rash of calls this week, egressing Peerless, with no RTP
stream during 183. First it looked like multiple vendors (or a CPE issue)
but checking SDP, calls exhibiting the behavior are originating from

Calls will receive a 183 Progress w/SDP, then 200 OK w/SDP, but no RBT or
media is heard during the 183. Tickets are being opened with Peerless (and
other ULCs who are using Peerless) but I'm curious if this is being
observed elsewhere...
