[AusNOG] Cisco SPA - Fax in Australia

[David Witham]

+1 to Andrews response. This is our approach also. Although if the fax is being sent across a public network sometimes you have to resort to t.38 and all its foibles.

Macca - I ask myself all the time why people still insist on faxing. And their machines are all-in-one with scan-to-email! Go figure!

The holy grail of faxing is a scanner and email....

Hi Joseph,

Best luck with these units is to disable anything smart and make sure the impedence settings are set correctly.

Our usual strategy is:

- disable silence suppression
- disable fax detection
- disable T.38
- set Australian impedance settings
- ensure only codec for negotiation is alaw

normally this takes it from about a 20% success rate on fax calls to around 96%.

Still looking for a "holy grail" solution.

Thanks,
Andrew

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
