Does support ICTFAX T.30 and T.38 FAX protocols?

Postby remses » Fri Apr 26, 2013 10:48 am

Hi to everybody,

I am new in this forum and in freeswitch, I usually work with asterisk.

I need to install a FAX Server. I am trying to test ICTFAX and have some doubts.

Is supported by ICTFAX both fax protocols, T.30 and T.38, by default?


Best regards,

Ramses

Yes, ICTFAX support both T.38 and T.30 Fax protocols. ICTFAX is built-over Freeswitch, so you just need to configure gateway in Freeswitch, tell ICTFAX about the gateway info and set the required channels variables. You are done!

Following link will tell you how to configure ICTFAX for T.38.

For T.30, you need to have a T.30 Fax hardware device that should be configured with Freeswitch. I, personally, haven't done that configuration. So might need to consult some Freeswitch guru about configuring T.30 gateway. Once it is done, ICTFAX will require just name of that gateway to send fax through T.30 protocol.

Falak, very thanks by your reply.

I explain you my scenary:

ISDN / PSTN / SIP Provider <-- Analog / ISDN / SIP --> Asterisk Server <-- Trunk SIP --> ICTFAX

The Asterisk Server acts as gateway between external network and the FAX Server (ICTFAX), working in passthru mode when it receive a fax to some DID of ICTFAX.

My question, and my doubt, are:

Will receive ICTFAX the fax correctly if sends it to him in any technology / protocol (Alalog-T.30 / ISDN-T.30 / SIP-T.38)?. Or I will need install something how spansdp o similar?

I have mounted the following infrastructure and it works, but have some errors:

ISDN / PSTN / SIP Provider <-- Analog / ISDN / SIP --> Asterisk Server <-- Trunk SIP --> Elastix (that have HylaFAX)


Best regards,

Ramses

We recommend you to configure your asterisk server for T38 pass-through, however if network latency between ICTFAX and Asterisk server is good then instead of T38 you can simply use G711 (alaw/ulaw) codecs for trunks.
