[hylafax-users] Hylafax + T38modem + VOIP Gateway

[Kimble Young <kimble@xxxxxxxxxxxxxxx>]

Has anyone managed to get hylafax + T38modem + a gateway apart from 
cisco working?

The unit in question is a mediatrix 2402.  T38modem negotiates properly 
but there are a large number of bad HDLC frames and other errors generated.

Ethereal dumps show that a large number of the hdlc-data packets are 
malformed and that the connection keeps training down in speed.

Faxes do generally make it through if they are short but each page can 
take up to 3 minutes instead of the usual 30-60 seconds.

I've tried going through their support channels but they aren't much 
help so I thought i'd ask if anyone has a t38 gateway apart from cisco 
working properly?

Apologies for asking on the hylafax list but I haven't been able to 
raise a response on the openh323/t38modem list.

t38modem is - 0.8.0
hylafax is either 4.2.0 or 4.1.8 (tried a few machines)
t38modem is run with:  t38modem -F -n  --old-asn -p ttyx0,ttyx1 -P 
T.38-UDP --route all@xxxxxxxxxxxx -o trace.log -ttt

config.ttyx0,1
