Calls Dropping every 2 hours help! 1

[mentallimit]

Hello all, I need all your help once again. I have a 8700 at my main site and a 8300 running 5 g700's at my remote site.

It seems that exactly 9:30, 11:30, 1:30 3:30 5:30 we drop every call in queue. It seems that calls that are talking to agents stay on the line. I have no idea what could be happening. Any help would be great!

I have a read a little about the protocol version being a problem. And we did just swing our PRI's from one CO to another. They tell me this is the set up they are sending me:
SGF
F,ESF,B8ZS
BMP Framing Format
ESF

Clear Channel Indicator
Y
BMP Line Format
B8ZS

Framed/UnFramed
Framed
Signalling Protocol
Q.931

THANKS IN ADVANCE!!

I just talked to my AT&T rep. and they told me the equipment is a Nortel DMS-100. Which protocol should I be running? A,B,C,D?

Let me ask you something...are other users affected? Can you make calls outbound during this time?

Is your S87xx setup with a control network?

Is the call center hanging off of a G700, or the S87xx?

Also did you make sure your gateways are set to sync off of the PRIs?

 

[mentallimit]

Users at the remote site are all effected.

I think my 8700 is setup with a control network...how do I check? Fairly new to Avaya.

The call center in question is off the g700's.

How would I check the gateways sync?

mentallmit,

Since calls in queue are the issue, looks like your 87xx may be doing an interchange. Typically, when an interchange happpens, you lose calls in queue.

Also, check your mgp config in each g700. do this by telnetting to the mgp, type root as login and pw as root.
do a "show sync timing and show sync source". this will tell you if you have a sync source setup.

 

[mentallimit]

How do I change the setting on the 8700 for that interchange? Or to make that happen off hours?

I will check the g700 right away thanks!

 

[mentallimit]

It looks like 2 of the 5 g700's did not have a sync source. So that is taken care of THANKS!

But would love to hear more about the "Interchange" and how to change that setting.

Problem fixed! Found a document on Avaya's support site, looks like a known problem...funny when I called into the helpdesk at Avaya they has never heard of anything like this before...


Problem description
When the H.248 Media Gateway Termination Audit runs (every two hours), processor occupancy briefly
becomes much higher than average. This can block call origination, and also slow down response on the SAT.
Resolution
Contact your technical support organization. Request and apply the latest 2.2 approved combo patch that
includes the Service Interrupting patch 11066, or request and apply the latest 3.0 approved combo patch that
includes the patch 11028. You can also upgrade to Release 2.2.2 or 3.1 or later of Communication Manager.
Workaround or alternative remediation
A workaround is to run the SAT command “disable test 1524”.
