[Freeswitch-users] DTMF problems

[Kerem Erciyes]

Hi Boris,

I have had same kind of problems with PRI circuits between Channel Banks  
and VoIP Servers due to static on the POTS line and/or too high gain  
settings on the PRI cicuit. Try playing with the gain settings on the  
Cisco 5350, maybe that can help.

Regards,
Kerem
