I face the following problem on incoming calls from my provider which uses Asterisk 126.96.36.199, our asterisk being 188.8.131.52. Incoming calls are not sended to the context set in provider sip.conf definition, but are going to the default context setted in [general].
Provider uses few IP’s for incoming calls which are not the one used for register.
Here are the logs:
