[Asterisk-Users] SIP One-way audio: == Forcing Marker bit, because SSRC has changed - trxtel.com
Dear list (and more specifically Bret), I am getting one-way (inbound only) audio when trying to place a SIP call via voip.trxtel.com (i.e. 18005558355@voip.trxtel.com). The Cli spits out "== Forcing Marker bit, because SSRC has changed" 5 times after atempting a native bridge. I realize this is most certainly a NAT issue, the * server is behind one. Sip.conf has externip=, and localnet=. Can someone explain what SSRC changing implies is going on, and why it affects NAT? This is actually the first NAT issue I have had with *, all other SIP calls have worked fine (I must be lucky). Sincerely, Brent A.

Sip.conf has externip=, and localnet=.google is your friend :-) We've already covered this on the list, it's not something that you should be concerned about (or even seeing). Later releases of Asterisk no longer generate this message, and when they do it is not marked as a warning, because it is not. -- Kevin P. Fleming Senior Software Engineer Digium, Inc.
