Suggestion Needed on using GSM to sip gateway with freeswitch in C#

I am considering using 2N® VoiceBlue Lite with Freeswitch to serve as a GSM to sip gateway that will route gsm calls to fs server for an IVR system to be built with C# anybody who has tested this or anybody with any suggestions or opinion?

What does your IVR system need to achieve? If it's routing call then you can do this fairly easily with the freeswitch dialplans.

Anything more complicated might require a programming language. I've used LUA in FS and this works very well. LUA is integrated well and there's a lot of help on the web for how to program FS using LUA.

2N VoiceBlueLite looks like a standard GSM gateway and calls can be sent from the 2N in SIP to FS. DTMF is handled by 2N with RFC2833 so this won't cause a problem on freeswitch.

You might find that you are getting double digits on Freeswitch - this sometimes happens with SIP so best practice is to explicitly state that you're using RFC2833 at the beginning of your inbound dialplan.
