Thanks for the response Vlasis. We run statistical analysis for FAS in our production routes.
This request would be for a controlled environment where I am using GrandStreams 488 to convert from Voip to PSTN. I was thinking that perhaps FS has a way to allow me somehow access to the Signaling portion of the protocol. If that was the case, I would be able to hack my way around it and perhaps ignore the first 200 I receive and not propagate it to the origination gateway. This is the setup I am looking at:
A => B => GrandStream Device => PSTN
SIP SIP
A/B - Both Gateways
This is a test environment I am using, something I am just playing with. So in every case I will receive a FAS from the GrandStream device.
Do you know if there is a way to launch an application from the DialPlan and have access to intercept Signaling; something that would allow me to see the messages coming in and make decisions based on them like propagate or do not propagate that message. I know this is a tough thing since I am literally asking for access to the SIP Stack.
I think those last two sentences describe a natural feature of a SIP proxy. I'd check out OpenSIPS to see if it has the stack-level control and functionality that you need. -MC
