hello,
everytime i restart asterisk, outbound calls work fine for about 300 seconds.
Then it fails.
Tracking down with tcpdump, suddenly after 300 seconds, the provider returns “forbidden”, while the options sip transmitted to the provider looks exactly the same (but some id’s). In the first 300 seconds, it returns an option sip and “ok” of subsequent transactions.
that is very strange and no clue how to solve that problem and not enough knowledge. I am under the impression that maybe the provider does not want the binding to be maintained and set a timeout. That would explain why it works again when restarting asterisk.
I am struggling with that for too long, it is time to seek help !
thanks
