No, at sip level does not make sense.

You can implement whitelists, blacklists, call screening ("dial 123 on keypad if you are a human"), etc...

That is application logic.

I would avoid messing with protocol on a such simple heuristics.

But, obviously, free to do it.

FAS is something that in Telecom nobody want, and I detect that if I don't receive  ringing (18*) from the provider, them will be a call with FAS and I would like to avoid this for my incoming calls. Make sense?


Thank You

Why?
Provider just answer (200) instead of ringing (18*), why answer with an error (503)?

Breaks sip logic...

Hi.


I was trying to get a solution for this but I can't find any online.


When FreeSWITCH received an incoming call it send the call trought a provider, but my provider sometimes send OK(200) without 183(Session Progress) and the call is answered.

I need from FreeSWITCH to detect this behaviour and send 503 instead of sending OK(200) to the incoming call.


This possible?

Thank you all for any recommendations

Abel.
