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 On Tue, 24 May 2011 15:11:08 +0300, Boris Kovalenko <boris@tagnet.ru> wrote:
Hello!
My network enviroment is: PRI --- Cisco 5350 --- FreeSwitch (Version 1.0.head (git-1c95ad9 2011-01-20 22-43-50 -0300)) --- AudioCodes MP-118FXS. There is an IVR on FreeSwitch where calling party may press a key for personal client line or wait for a secretary. Sometimes (as client said) the call to line 5 is placed to line 3 (as I undestand DTMF 5 is recognized as 3). How may I detect and solve the problem?
