Hi all
I'm trying to integrate CW on a custom board and to use T38Gateway
application.
The test scenario is depicted here below
----------------------------------------
-------------------------------------------
G3 Fax -------->FXS port Custom Board CW based |
--------SIP-Proxy------| Custom Board CW based FXS port |
----------G3 Fax
----------------------------------------
-------------------------------------------
The Tx CallId is 207, the Rx CallId is 308. On both Callweaver PBX
T38gateway has been used to handle the call (Tx and Rx side).
In the test done the fax has been sent from 207 to 308.
The G3 Fax are a couple of analog modems connected to PC
I have attached both a capture of the network traffic sniffed and the
log taken from Callweaver
My feeling is that the SIP sessions has been established correctly and
the switchover happen succesfully. Anyway when the couple of CW try to
exchange some T38 packet, some error occurs and the fax transmission
fails. I cannot see the training sequence, but many fcs-bad packet have
been transmitted by both sides. Please help me to understand better what
happens and where is the problem. could be an endianess problem? my CPU
is a bi endian architecture.
best regards
