[Asterisk-Users] Receive calls with Aastra 480i phone problem

[Jean-Francois Theroux]

Hey guys,

	We bought a Aastra 480i phone for our boss. This looks like a nice 
phone, but we have an issue with it.

	The issue is this: the phone is able to place calls. But as soon as the 
phone receives a call, you are able to answer it. But then, 2-3 seconds 
later, the call is dropped.

	The extension works, because I've put his Gnet phone back until I 
figure out what is wrong with this phone.

	I tried changing the dtfmmode for that particular SIP extention. To no 
avail. I'm running out of idea, now. Anyone ever configured those phones?

Cheers,
