[AusNOG] Cisco SPA - Fax in Australia

[dean at faktortel.com.au]

Hi Joe

You can try these settings.
I use these settings for pap2t and spa3102....etc. should be similar to
spa122. if i dont have a t.38 gateway

3 Way Calling: no
Echo Canceller: no
Silence Suppression Enable: no
Call Waiting: no
FAX Disable ECAN: NO.
FAX CED Detect Enable: YES
FAX Enable T38: NO
FAX T38 Redundancy: 0
FAX Tone Detect Mode: Caller or Callee
Network Jitter: Very High
Jitter Buffer Adjustment: Disable
Preferred Codec: alaw
Fax Passthru Method: reinvite

These 2 make a big difference for me..

RTP Packet Size to 0.010
FXS port impedance to 220+820|| 120NF

Hi list,

  Trying to have some luck using faxes behind Cisco SPA ATA's, in particular
testing with an SPA122. I can get the unit to detect its a fax coming
through, but often they don't begin communication between the
2 endpoints, or if by luck they do I get a comm error.

  T.38 is enabled, NSE enabled, also tried with no NSE enabled.

  Anyone had luck getting these units to work in AU ?

Thanks,
Joe
