[Linphone-users] problems with asterisk

[Jon Lawrence]

Hi,
I'm trying to use linphone to make sip calls through my asterisk server.
Asterisk version is 0.5.0
linphone version is 0.12.1
linux distro is gentoo
kernel is 2.4.23

I can register to the * server without problems but whenever I attempt to make 
a call I get a '407 proxy authentication required' message.

Anyone any ideas what I can do ?

I don't know if this is a problem with my asterisk setup or with linphone.

TIA
Jon Lawrence
