That confirms we're good with the setup but wanted to check just in case. > Sipx ONLY supports t.38. So if your provider supports t.38, it should > work just fine. This is where things get weird. The provider asked what protocol we wanted for SIP traffic but they don't provide end to end SIP services, it's only between their own on site route back to their network. They don't yet offer the usual SIP trunks. I specified G.711 to cover the bases until I find a T.38 solution for my fax server but incoming in my main concern which is why I had a sudden need for 4.4.0. Thing is, they are handing off a standard PRI trunk to the mediant so faxes and calls are coming in over G.711. Can the mediant work any magic that sipx would accept? > On Sun, Apr 24, 2011 at 6:35 PM, [email protected] <[email protected]> > wrote: >> The wiki seems to touch on lots of troubleshooting but I can't seem to >> find an answer on the following. >> >> The new 4.4.0 system is connected to what sounds to me like a weird >> hybrid setup. >> >> The provider has a T1 line between their network and the system site. >> At the site, they are using a router which is breaking out to a full T1 >> and a dynamic PRI. >> The PRI is connected into a mediant 2000 which in turn will talk with the >> 4.4.0 sipx box. >> >> The hybrid part to me is that the PRI portion should simply be that, a >> PRI, yet, they needed us to specify the protocol to use between the >> router and their site.
