Yes Boris, try setting it lower incrementally and see if it helps. There might be problems related to gain + echo on the line that confuses DTMF detection, so check if the line has echo as well. Also sometimes I have seen that the remote calling party has a POTS line with too much static it can confuse DTMF detection. On other VoIP systems we solved this problem by spying on the channel e.g. http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_eavesdrop can be helpful in debugging the situation.

Kerem, are You talking about input gain parameter? AFAIK it is 0db by default. Would You recomend to set it lower?

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
