Hi all, For some reason VSAT or Satellite Internet services are not mentioned (or searchable) in this list's archives. I thought I'd let you know that I tested Asterisk using IAX (not IAX2) to make a phone call from an analog phone hooked up to an Asterisk system behind a Linksys router connected to a Gilat VSAT satmodem, and it worked.
The "other end" (gateway) is a P200MMX with a X100P FXO card. I have bi-directional calling set up so that the VSAT-phone can make outbound calls using the X100P in the gateway, and if the X100P gets a ring it answers and transfers the call to the analog phone on the other side of the VSAT. There is about a 1-2 second propagation delay in voice from the VSAT phone, as expected. The echo is not bad at all, and the voice quality is quite good. I don't think the VSAT network was very busy so I don't know how well this will work if the available bandwidth is less. We are not using the G.729 codec - just gsm. I have tos=reliable set in iax.conf. I didn't get disconnected during my test calls, but they weren't very long in duration. I haven't tried a fax but maybe I will. Anyway congratulations Mark et al on your fine work making such a robust VoIP system. Thanks! -- Jim Ockers, P.Eng.
