[Freeswitch-users] ESL: not bein able to determine when SIP gateway is down when originating a call

[Peter Olsson]

In this case there should at least be a BACKGROUND_JOB event with the result from originate (INVALID_NUMBER_FORMAT) - are you monitoring these events? If you want a specific event fired for "gateway down" you will have to create a patch for this.
