[cisco-voip] Fax Server Recommendations

Sat Nov 16 07:14:07 EST 2013

Hi Travis,

Thanks for the feedback, I don't have access to the Remote end Fax server, I
will need to speak to the customer at the far end on Monday and request a
wireshark trace.

In your experience what do you believe could be the issue, obviously the
successful fax transmission (10 Pages) over pots dial peer give any
indication as to the setup of the Right Fax Server.

Regards

Charles

Hey Charles,

your config for the cubes looks fine, as i can see both t.38 and g711 pass
through enabled on 9913 and 9914 respectively.

can you do me a favor, and send me a wireshark trace of a failed call? just
run the trace on the rightfax server

Hello Travis,

Would you be kind enough to advise on the following issues with Fax
transmission via a SIP ITSP and you're recommendations.

I  have an issue with sending fax to via a SipTelco, there are no issue
sending the fax If the Fax is send out via a Pots dialpeer ISDN or Analogue,
however the Primary route is via a  Siptrunk to a Cube voice gateway then
out the SIPTelco (ITSP). The Fax Protocol of Choice is T.38, I have also
tried Fax Pass-Through i.e. not (Fax Passthrough, Cisco). But still no Joy.
It quite clear the issue lies with the inter-connect via the Sip ITSP & the
remote end Efax Server. The FoIP Protocol is set  on the Voip Dial-peers, I
have configured 4, 2 for each ITSP which allows me to carryout test using
either Skype or Sipgate  as the ITSP (T.38 Fax relay or Fax Pass-through)
What is your recommendation.

I attached the configuration of the Dial-Peers.

Thanks in Advance.

used Xmedius at my previous job and have Right fax at my current job.  Both
do the job, but If I had the option..... I would definitely go with Xmedius.

Does anyone have recommendations about a good fax server solution that can
be implement using SIP trunks? Or are there any that we should stay away
from based off personal experience?

We are in the beginning stages of exploring a fax solution and I was just
looking for any suggestions.

FYI: We are running CUCM (8.6.2a) and currently we are using VG's for our
faxes today.

Thanks
