[Freeswitch-users] FreeTDM: ISDN-Port (D-Channel?) useable only one time

[Markus Mueller]

Hi Freeswitch users,

if I get an incomming call (FAX), the call is answered and successfully 
processed, this channel don't get any new calls in until the channel has 
been reseted by "ftdm stop" and "ftdm start".

Please see the log file on

http://projekte.priv.de/freeswitch/log

You can see there that a fax is comming in on three ISDN lines, but only 
accepted on one of them. On the first fax it comes in on all three ISDN 
lines, on the second fax only on two ISDN lines, the third fax is only 
comming in on one line and all further faxes can't be accepted. After 
resetet with "ftdm stop" and "ftdm start" it is comming in again.

Further config files can be found on

I am using Debian Squezze with the dahdi-source package to access the, 
libpri-1.4.12-beta3 and the git fetched with "git clone git:/ 
/git.freeswitch.org/freeswitch.git " from "Wed Mar 2 20:50:33 2011 
-0600" (last entry in git log). Als hardware I have three singleport HFC 
Cards:
