[Asterisk-Users] Fax over 2 bridged TE110P channels

Tue Apr 4 02:11:24 MST 2006

Hi,

I have an asterisk installation with 2 E1 cards

Software version is

Asterisk 1.2.6
Libpri 1.2.2
Zaptel 1.2.5

I'm having problem with fax transmission, let me explain better my
setup:

My fist TE110P E1 card is connected to the telco line
the second TE110P E1 one to an Nexspan PBX

so the server is basically sitting between the line, and the pbx.

every call coming from the line is simply redialed in the pbx
every call from pbx is simply redialed to the line
no answer is done

All is working great with voice, but faxing often results in error, both
receiving and sending.

I have disabled echo cancel, and also checked for interrupts problems
and other common misconfiguration problems.

Would someone please help me sort this out ?
I'm suspecting sync problems ...

Tnx for any help!

Following are some debug and config files

zaptel.conf

loadzone = it
defaultzone = it

bchan=1-15
dchan=16
bchan=17-31
