Is it possible to connect an FXT009 including the ethernet extension card to a PBX and receive calls over SIP/H.323?
Probably a noob question but I would appreciate any guidance on the subject. I would also be interested in using other OpenAT modems to achieve this.
SIP/H.323 is common VoIP protocol and based on TCP/UDP for management, RTP for data stream.
So either you have an host controller with SIP/H.323 stack running and use FXT009 as modem; or you can implement these protocol using WIP library and use FXT009(or other OpenAT device) in standalone mode.
Please refer to the spec of both protocols, e.g. SIP - RFC 3261, for details.
Still, if you are planning to implement and run SIP/H.323 stack inside FXT009 OpenAT for voice call, you may consider the audio interface as which the built-in analog audio may not support the SIP/H.323 audio stream.
Hope it helps and let us know the progress of your development.
Hi, lotam and thanks for your reply. Can you give me some more details on the first solution you proposed because I don’t quite follow. If I understand correctly you’re suggesting to receive the call in a host machine and then pass the call to the modem; how is that possible? will the modem recognize this as a regular incoming call?
