CCMA Trunk allocation trouble for networked calls

[mikeyb123]

Hi All,

Here's a goody....

2 sites, both at ccms 6 su 05 all patched to current levels, cs1k's @ r4.5 all patched.

Call is placed into site A gets queued to a netowrk skillset and is answered at site B. in CCMA we are seeing that there are trunk allocation troubles and the site B gets filtered.

We have capacity on the links between sites, dialable DN is good. Calls placed the other way round work all the time, anyone seen this before?

It's not getting any smarter out there. You have to come to terms with stupidity, and make it work for you.

Yes - Are you getting site filtering (trunking troubles) or skillset filtering (skillset closed)?

I know you've probably done this, but you'll need to check your NACD settings and make sure NACD works both ways at the switch level. Then double check your trunk settings at both switches and pay attentions to any differences.

Finally, make sure you are on the latest and greatest updates. I think SU 06 is the most recent. We did have issues like this last year and we had to get a fix from Nortel (after doing all the above first).

we only get trunk filtering - NACD works both ways, it was one of the first things we checked. After a long weekend of testing it looks like it's the meridian causing this. we now have a diagnostic patch to see what's going on.....

When you do find out, please post the solution here. Interesting problem.

will do - we are still testing and having trouble recreating this - looks like a load related issue

By load, do you mean the trunking is reaching capacity going from A to B, but not B to A?

Are your calls allocated 50/50 in the network or are they skewed (site A gets 70% of calls/Site B gets 30%)?

still no news on this. Nortel have come up with some incorrect messaging or incorrect intrepretation of messaging between ccms and cs1k but nothing else so far.

Have you tried increasing the timers to allow more time for the to callset up?
