Hi all, I am absolutely new to callweaver, coming from a 2 years experience on asterisk
I am trying to use callweaver in order to use its T.38 capability.
I installed callweaver and arrange sip in order to handle T38 traffic.
Then I tried to fax against 2 T38 capable devise:
1) Grandtream Handytone 486
2) WellGate 3701B
I had no success with none of the two.
On the wellgate there is the possibility to remove the ECM, on the
granstream I wasn 't able.
The fax came from an hylafax, using iaxmodem on an asterisk iax2 connected
to the callweaver via a IAX2 channel: it should be an ordinary fax, as it
were coming from the pstn, and callweaver should act as a gateway,
converting traditional analog fax traffic into T.38 traffic, sendig it in
SIP to the ATA (WellGate or GrandStream)
Here I attach a part of full log, obtained with the welltech
There are about no differences using th GrandStream, apart form
T38MaxBitRate 9600 on the grandstream

************************************************
It seems to me they "try" to talk T38... but nothing exited from the analog
faz physically connected to the ATA !
any help will be greatly appeciated,
thanks in advance,
