[asterisk-users] Voipbuster not ringing, other SIP peers are ringing...

[Francesco Peeters]

Does anybody else see the same behavior for VoipBuster connections?

When I trace one of the other SIP peers, I see it sends this message:

However when I dial exactly the same from VoipBuster, I see this instead:

As you can see, there are different packets being sent, and in the 2nd
case, there is no "is ringing" message, which is rather irritating...

Any suggestions would be appreciated...

TIA
