> Our Asterisk is behind an NAT and has an public ip. Sometimes our public ip address changes. Asterisk sends an REGISTER all 480 seconds.
> If our public ip address changes and Asterisk sends an re-REGISTER, our provider sends an OK. But asterisk does not realize it. Instead asterisk sends multiple times a new REGISTER and gets always an OK. After some time it logs "res_pjsip_outbound_registration.c:761 schedule_retry: No response received". Why!? Asterisk received multiple times an OK!
> After some wait time it retries again, gets an 403 Forbidden from our provider and permanently stops outbound registration.
> Chan_sip handle properly this situation.
> Attached a log from the communication between asterisk and tel.t-online.de.
