[reSIProcate-users] Sending INVITE as Server

[Amnon David <amnon@xxxxxxxxxxx>]

Hi,

I'm sure what I'm trying to do is quite standard, but I can't seem to 
find any reference to how to achieve it in resiprocate:

The basic idea is receiving a fax - in a nutshell, the gateway 
application receives an INVITE from the remote endpoint, the codec is 
negotiated and then starts transmitting audio to the telephony endpoint. 
Shortly afterwards, the gateway application realizes that the telephone 
is really a fax machine and therefore initiates an INVITE with an SDP of 
T.38 back to the VoIP endpoint that initiated the call. At this point 
the VoIP endpoint, sends back an OK - but the problem is that this OK in 
not propagated to the resip application's InviteSessionHandler 
callbacks, so there is no way for my application to ACK it.

I can send resip stack and wireshark logs (where everything works fine 
until the OK response for the fax INVITE), but just wanted to make sure 
that I didn't miss a trivial solution before wasting bandwidth...

Thanks for any help,
Amnon
