Hi,
The following case occured:
Caller
-
SER
-
Called party
->INVITE->
<-TRYING<-
->INVITE->
->INVITE->
<-TRYING<-
<-RINGING<-
<-503<-
->ACK->
...
I think that the 503 response was caused by the second INVITE of SER. When SER
sended this INVITE the msg_send function returned 0 which means success, but the
tm module processed it as if it were an error. I captured the massages, so I'm
sure the INVITE was sent correctly.
