When someone from the outside leaves a voicemail, the voicemail is VERY distorted. Almost sounds like a broken speaker. But it's not consistent! Happens only occasionally... I've checked the same voicemail from different IP phones and I get the same result. ANy ideas? Could it be the H.323 gateway? (I'll post the router config)
Here is the topology:
PSTN---PRI----3640--h.323--3524----CM1 (Unity and IP Phones connect up to the 3524 as well)
Here is the router config:
k wr t
service timestamps debug datetime msec localtime
service timestamps log datetime msec localtime
logging buffered 4096 debugging
no logging console
no logging monitor
aaa group server radius safewordGroup
server 172.16.1.185 auth-port 1812 acct-port 1813
aaa authentication login safeword group safewordGroup local
Perhaps you are having intermittent duplex mismatches.
Especially since you are using a VLAN trunk interface between the router and the switch, you want to hard-code the speed and duplex to 100/full on both the router FastEthernet interface as well as the switch port.
I need your help please. Having a similar scenario as yours but I'm not familiar with the 3640 config as H323 device. My scenario is as follows:
So I assume that 3640 is talking h323 to CM1, am I correct ? and "dial-peer voip" statements are for voice connections to CM1 ? do you have FXS ports in your config because I'd seen "dial-peer pots" statements ? Can you post the "show diag" so I know what interfaces in your 3640 ? Thank you very much.
On the 3640, i have a NM-2HDV (with 2 T1 controllers) 1-NM-2V (1- 2 port FXS for polycom conference phones and 1-2 port FXO for backup PSTN access. It also has a Fastethernet interface as well. I can't do a show diag today as I'm not at the customer site.
What version of Unity and CCM are you using?? I have noticed problems like that in versions prior to 2.4.6 with distortion... 2.4.6 and the latest TSP should take care of that...
In addition, the recording level or playback level may just be too hot... there is a utility on www.answermonkey.net called wavegain that can adjust the appropriate registry entries to modify wave levels.... just beware that even the the lead Unity Product Architect wrote the utility, Cisco doesn't officially support it...

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...
