[Freeswitch-users] False Answer Supervision (FAS) - Question

[Alfredo Quiroga-Villamil]

All:

A while back I tried to solve a false answer supervision issue I was
intermittently receiving from underlying carriers. Back then I tried
to find a solution using asterisk but had other pending things and put
this off until now.

Does anyone have any recommendations on how to possibly handle or get
around FAS using FS. If I am not mistaken what would be needed is to
have something that upon receiving the first 200 message, it simply
ignores it, never propagating it and waits for the next 200. I can
control this now a little bit better since it's only happening when
the calls are sent to a couple of GrandStreams (FXO).

My idea is to perhaps write a little application and add it to the
DialPlan. The little script/app. would have the logic to ignore the
first 200 and hopefully get around this issue. Is that something that
is doable? Any other ideas on how to do this assuming is even possible
to do it?

Thanks in advance,

Alfredo
