Ok, some more questions....

I am using asterisk 1.4.15 with 1.4.11.4 libpri and 1.4.12.1 zaptel

Do you think i should change to a more recent asterisk and libpri and 
dahdi instead of zaptel? I suspect that zaptel might be causing the 
problem, as i am having trouble to start it again after an asterisk 
disconnect

asterisk-video*CLI> module load chan_zaptel.so
[2010-12-02 11:25:27] WARNING[9033]: loader.c:362 load_dynamic_module: 
Error loading module 'chan_zaptel.so': 
/usr/lib/asterisk/modules/chan_zaptel.so: cannot open shared object 
file: No such file or directory
[2010-12-02 11:25:27] WARNING[9033]: loader.c:646 load_resource: Module 
'chan_zaptel.so' could not be loaded.

If i reboot then everything will be fine and i will be able to make 
normal calls

Also i read about a patch in libpri in order to make outbound 3g calls, 
which in fact is what i want to do. I havent applied any patch to 
libpri. Should i and if yes where do i get it

Finally it is a pitty that there is no little wiki about this wonderfull 
project, i am having difficulty to find dialplans to test, like how to 
use app_transcode and how to set up test environment e.g. how to make 
sip to 3g and vice versa

Thank you in advance

Regards
