052248s When a narrow WAN (Wide Area Network) link to a
remote office terminates to a G350 or G250 Media
Gateway, calls on the media gateway might experience
jitter (choppy voice transmission), voice transmission
delay, and interrupted voice transmission.
Set the DSCP/CoS values for audio and signaling on the
media gateway to 46/6 and 34/7, respectively. To do
this, you can:
- use the commands 'set qos bearer' and 'set qos signal'
on the media gateway; or
- set the values on the ip-network-region form for the
region containing the media gateway, and then run the
command 'set qos control remote' on the media gateway.
To see what the local (media gateway) and remote
(primary server) values are, and which values are in use,
run the command 'show qos-rtcp' on the media gateway.

On a G350 or G250 Media Gateway, an ISDN Multitech
modem (IWAY version 3.34L of MTA128NT) goes out of
service while operating at 230Kb/sec full duplex after
transmitting packets of about 64 bytes or smaller for a few
minutes, or after about half an hour of transmitting voice
traffic.
Reboot the modem.
You can reduce the frequency of this issue by avoiding
the use of the modem for routing VoIP bearer traffic.
Watch for a newer version of MTA128NT from Multitech
that remedies this issue.

different release, and then download the desired release.
