Summary:                    No Re-Invite message from Asterisk to the peer when
trying for FAX pass-through
Description: 
I have been trying to test fax pass-through with Asterisk.
The scenario is like this. 
Two fax machines are connected to the ports that are configured with
Asterisk server.

When i am trying to send fax from one port to another port, the receiving
port is detecting the fax tone, after initial call set up, and sending the
re-invite to change the codec to G711(PCMA), it is receving the response
from the Asterisk (Trying and 200 OK), but there is no re-invite message
from the Asterisk server to the peer(in this case fax initiator). 

i am expecting the re-invite message from the Asterisk to the peer to
change the codec to G711(PCMA), but it is not happening. what is the
problem i did not understand. 

I have tried with canreinvite=yes and no and nat=yes and nerver. but the
behaviour is same. no re-invite message from the Asterisk to the peer.


Could you please help me to resolve this issue.
