[Freeswitch-users] Sangoma FreeTDM in NET mode immediatly restarts interface

[kietlak]

I try to make external IVR on E1 Siemens Hicom Trunk using Sangoma A102.
E1 port connected to Telco works without any problem.
E1 port connected to Siemens doesn't start because is restarted as below.

Where I have to look for the reason (and solution) of this problem ?
