[cisco-voip] Fax Problem after Hardware upgrade

[Ahmad Cheikh Moussa]

Hi!

I have a strange problem with my fax.
Sometimes we receive a fax, where one line
is missing or the line is not readable.
This error occus everywhere. Sometimes it is at the
top of the fax, sometimes at the end of it.
So it is really hard to isolate the exact reason for that
problem.

What I have done ?
I made a hardware upgrade from 3640 to 2821. I use now
the 12.4(3) AdvIPServices with 1 x PRI and 1 x VIC2-BRI-NT/TE
Before the upgrade, with the same modules and with the same
configuration, there was no problems receiving a fax.
I used 12.3(7)T. Now after the upgrade I have the problem
like it is described above.

Did anybody had a similar problem ?
Any ideas ?

I also tried 12.3(14)T3 AdvIPServices, but there was the
same behaviour.

Here a config cut of my voice-gateway:

interface BRI0/1/1
  no ip address
  isdn switch-type basic-net3
  isdn protocol-emulate network
  isdn layer1-emulate network
  isdn incoming-voice voice
  no isdn outgoing display-ie
  isdn skipsend-idverify
  line-power


voice-port 0/1/1
  compand-type a-law
  cptone DE

dial-peer voice 51 pots
  max-conn 2
  destination-pattern 6..
  direct-inward-dial
  port 0/1/1
  forward-digits all


Thanks in advance,
  Ahmad
