[Asterisk-Users] Microsoft Portrait 2.2

[Marc Fargas]

Has anyone suceded using Microsoft Portrait with Asterisk? I've seen only
one thread about that on the list and it's a bit old, maybe someone has
succeeded lately..

It successfully signsin onto asterisk but I could make no calls with it, I
can only see these: 
* Got SIP response 481 "Call Leg/Transaction Does Not Exist" back from
X.X.X.X (clients ip address)


Any clue?

Thanks
 Marc.
