Im getting very distorted voice calls while using a VIC BRI voice port. I have tried several Images, gain controls and have even changed all hardware components, ie the 2621 -- NM-2V -- VIC BRI S/T TE. I have even used an FXS in the router with a phone to bypass any CM or Voip issues (still the same problem). I have a 765 with voice ports that I have used to check any line issues, and I dont the voice is clear. Anyone seen this problem ??
I have 12.2.3 running at the moment but I have had 12.2.2XG, 12.2.T1 and one or two others. NO qos required has this is a 2610 (h323 gateway) in a lab connected to a switch with only a CM and 4 phones. The 2610 has the VIC-BRI with dial-peer set to 9T for outgoing calls. The problem is with every call over the BRI voice port, either Voip or via a FXS installed in the gateway also.
If the voice sounds as if you are talking under water then it probably relates to the G711 type used on the BRI. Ensure that the CP Tone is set correctly for your country and if fails to solve it then use the Compand-type command to set the G711 to that used in your country (Default is G711uLaw I think)
Thanks for that Steve, I did originally think about the compand-type but made the same assumption that if you change the cptone it automatically changes compand codec. After seeing your comments I checked sh voice port and saw that the compand type was still ulaw. The images I used didnt support compand-type command so I have had to play the image hopping game , Im now using Version 12.1(5)XM4 which allows the change.
So this is one to watch for if you need to change PCM types on basic rate voice ports. Thanks again !!
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
