[asterisk-r2] [r2 dropped calls]

[Juan Pablo Villarreal Montoya]

Thanks for your answer.

I don't know what could be wrong on the line,  but calls from Siemens PBX to
asterisk have no problem.  Also calls from Siemens PBX to PSTN through our
asterisk server are ok.  So if the problem is physical, shouldn't outgoing
calls being dropped also?


thanks again.
