[Freeswitch-users] Help debugging INVITE with provider

Hello, 

I'm having trouble to send/receive calls with one of my
providers. 

Freeswitch says the reply sent by provider has the session
information incorrect, then the provider replies the calle is busy (which
of course is not). 

The sip trace follows. 

Anybody can help ? 

François
