I am having problems with False Answer Supervision (FAS) while using Asterisk and Digium FXO cards.
We are sending phone calls to Russia from a USA Gatway/VOIPswitch. The serverers in Russia use Asterisk utilizing Didium 4 port FXO cards. There are 3 cards per server (12 ports). We have twelve phone line attached.
The problem is when Asterisk selects/seizes a channel/port to dial out a call it gives immediate Answere Supervision to my client even though the call had yet to be dialed at the server in russia. it showes answered even though there is ring no answer. busy ton, etc etc.
I have been told there might mbe a patch or a solution for this.
$$ to anyone that can help. PLease contact me at email@example.com ASAP…
