[Asterisk-Users] Fax over TDM400 and E100P disconnects

[Michael Løjtnant]

Hi all,

I am having some problems getting my fax-machines to work properly. I can make them dialup, and they cal also recive calls, but very often they disconnect during the data-transfer. Anyone got some ideas?

The setup is like this:

Pri <-> E100P <-> Asterisk <-> TDM400 <-> Fax-Machine

I have 1xE100P, and 2xTDM400

There is no errors writte in the Console, nor in the sys.log

System:
SuperMicro with P4 2.53GHz
512 MB Ram
3Ware IDE Raid Cont. (Running Raid 5)
1 x E100P
2 x TDM400
1 x Fritz! ISDN Card

Kernel-2.6.8.1 (Running ACPI, and Preemptible)
Asterisk, Libpri and zaptel is from stable 1.0.2 release
