Does T.38 fax can go faster than 9600bps?

[lpchouinard]

From what I found it's supposed to, but I can't get my SR140 virtual fax board to send and/or receive over 9600bps.

We are running CM 6.3 and the SR140 is using h323 to talk to the CM.

MG is a G450 (MP160). If I force the SR140 to g711 instead of t38 and set the codec to use v150 for the modem and set FAX to off I can get up to 33600bps... If this the right way to do it?

33.6 is nice, but we would be happy with a reliable 14.4. If you need more info ill provide it.

Thanks

Possibly up to 14.4, but depending on release, yes, it can be capped at 9600bps

A current voip/foip/moip document from Avaya might help you there, but I **believe** the long and the short of it is over 9600 is treated as a modem with regard to your codec sets and isn't seen as t38 anymore.
