Hi everyone, I’m new on pjsip and try to register one provider.
The register is ok and I always can make a call.
When I make a call after that i can receive calls but after a few minutes the incoming call does not even reach the asterisk. If I do another outgoing call, can receive a call again.
Are you behind NAT? If so, then the device doing NAT may be terminating the UDP port mapping so incoming traffic is not sent to your Asterisk. You can try setting “qualify_frequency” on the AOR to 60 to have Asterisk send an OPTIONS request every 60 seconds to keep the UDP port mapping active.
