Nortel 11c connected to Asterisk

[Elendil326]

Hi everybody

I've managed to make the connection Nortel -- Asterisk and calls from Nortel to Asterisk come well, but Asterisk to Nortel rings and rings, but when you try to answer it disconnects inmediatly.

I'm suspecting that the problem has to do with the parameter faststart of Asterisk, because the debug errors seem to have to do with it. Is there a configuration to make the CS1000 support the faststart of asterisk?

Thanks a lot for you answers.

The error that comes when Asterisk call Nortel CS1000M is the following:

In the page

http://www.voip-info.org/wiki/view/Asterisk+Nortel

tells the following:

[...] You'll get codec-problems (packet/frame-size incompatibilities during OLC-Handshake) with oohH323 and oh323, so NuFones h323 is your friend. [...]

But I'm not really sure what is NuFones, can someone please help me?
