Hi everybody.
First of: Does not seem that i am able to compile callweaver 1.2.1 or RC
on Centos 5.4 with PAE-Kernel.
Barring that i have compiled 1.2.1 SVN r5600 with the standard kernel

Main Problem:

Faxing does not work properly. Neither in T.38 or Passthrough.
Sending a fax from txfax does work, albeit slow.

My dialplan
[testfax]
exten => _.,1,T38Gateway(ZAP/g0/${EXTEN},300,tr)


Fax initiates

exit with ANSWER


Whats cooking. Tried with 3 Devices: Linksys SPA2102, Planet ATA-150 and
lastly Grandstream HT286

Seems Like T.38 Faxing still doesn't exist, or am i as useless as
previously suspected.
Any help appreciated.

On the strange side.
Once a call has been routed in from an PSTN (PRI channel) it seems like
zap show channels does not get updated after channel no longer exists.
