S8300 reliability - problems with reboots and MED-GTWY error?

[bbednar]

Hello,
we have a small (20 agents) call center, running on IP on Avaya S8300 with G700, AES, CMS server and Witness for recording. It is just working for almost a year. It keeps having problems with reliability (It is much less stable than our main PBXs - old Definits). Do you suffer the same?
1)It used to do some auto reboots (also during the call center working hours) about once a month. That was solved (it seems like that) by aplying latest patches by the Avaya local concractor.
2)About twice - witness stopped recording because of loosing the softphone connectivity to CM. Only reset system helped.
3)Today the CM stopped working - all witness softphones lossed the connectivity, agent ip-stations didnt have dial tone... For example display errors showed MED-GTWY error type 769 at the time, when it stopped working. Only reset system 4 helped.
Is that standard? Don't you know, what the MED-GTWY error is?
Thank you
BBednar

bbednar,

something unusual i'd say. make sure you're running the latest communication manager build and all firmware versions are up to date. as for aes, it had problems like you described but they were fixed in 3.1.2 version of aes. update your server to this version.

MGTY Error usually means a loss of network communications between the Media Gateway and the Media Server....

sjforcum,

depending on the size of call center i would say that it is not distributed so most probably the media server sits in media gateway. smells like software/firmware trouble not network one.

It sounds like a network connectivity issue between the Media Server and the Media Gateway.

Like pointed out previously make sure you've got all patches up to date.

Thank you for answers. The network connectivity should be OK, because it is all on LAN in one building (cisco-switched). We will check again if we have the latest patches on all the sw. But we had it all patched about 3 months ago and I don't know about any new patches released. I'll try to find them.

I think it's probably the network connectivity WITHIN the Media gateway, not within the cisco network...

let talk in plain text

the pbx is the media gateway (the big pox)
in slot V1 there is the media server
the media server is the brain where the software communication manager is installed on
so the pbx is two things in this case

1)communication manager on the board in slot V1
2)G700 media gateway (the big box)
they communicate with each other

that communication probably does not go right
this can be a firmware issue
every board withing the G700 (gateway) has its own firmaware
the media server (in slot V1 with communication manager installed) also has its own software level
evere firmware/software needs to be up to date and needs to match
this needs to be because it is designed to work with each other
