Hello Together,
i just got FreePBX running yesterday.
Everything is working fine. I am using my Android Phone as SIP Client. External calls (incoming and outgoing) are working fine.
Only one number is giving me headache…
When i try to call that number, the Asterisk Status says “Ring” and i can hear the ring tone… But that is a number where a computer picks up the call after 1 oder 2 seconds and after 12 seconds just hang up.
So what is happening here:
I dial the number, i hear the “Ring” tone for 12 Seconds and then the call gets terminated.
It seems like Asterisk is not recognizing that the call has been picked up on the other side??
The Trunk is not the problem - because i can call that number from another system with the same trunk.
Anybody with an idea what could cause that strange behavior?
Thanks and kind regards
