issues<BR></FONT><BR></DIV>
<DIV></DIV>Hi<BR><BR>I have a customer who's recently installed a rightfax
server into their network. I've configured their H.323 gateway for T.38.
Inbound faxes seem to work fine but outbound faxes fail about 90% of the
time. I thought it may be a super G3 issue but unfortunately the gateway
does not have enough flash to load the 12.4(T) image. While we're waiting
for a flash upgrade I asked the customer to work with rightfax on the
issue. They haven't been all that helpful but they did disable V.34 and
verified that the compression method was set to group 3. To me this should
mean the rightfax server should negotiate 14.4k and any super G3 fax machine
would train down to that level. Am I correct in this assumption?
<BR><BR>If so, I'm not sure what would be causing the problems. the T1
controller and ethernet interface show no errors. I can tell from the
debug output that the correct dialpeers are being matched and that the DSP is
downloading the fax codec for these calls but the outbound faxes seem to always
fail after the first page is sent. <BR><BR>For my dialpeers I have the fax
protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none and fax-relay
ecm-disable commands. The gateway is a 2651XM using the voice aim and a
VWIC-MFT-T1 card. It is currently running 12.3(11)T11<BR><BR>any thoughts
or suggestions would be appreciated. <BR clear=all><BR>-- <BR>kris seraphine
