I have an ongoing issue with a customer using an IPOffice 406v2 plus mostly Analogue phones on a V230pots unit. THey have two RPI cards and TWo BT/REdstone ISDN30e services one (the 1st service) has 30 channels enabled the other has 5 services enabled and the clock source is on the second service although it has been set to the other up until six months ago.
The problem is we loose the ability to dial out if 30 users try to dial out at roughly the same time and in fact the second service works fine for any callers after 30 calls. We can actually simulate this fault by making everyone dial out at the same time. normally you don't notice the problem until nearly 30 people try and dial out basically.
BT have done trend tests on the service and have said they can find no fault, they have said when this fault occurs they can't see the phone system talking to the header unit but I have no evidence for that as BT are reluctant to show us the results of the traces they have done so I only have there word for it.
Before you ask the obvious all the kit has been replaced at least once sometimes twice over a two year period to eliminate this fault but to no avail. All the software has been updated from 3.1 up to 4.1 something and at no time has this helped.
For te sake of ensuring this problem is not down to kit i plan to upgrade to 4.1.15 and all the files for VMPRO and PMLite to ensure they are up to date and swap the PRI cards round to eliminate these items but I am pretty convinced this is a BT fault.
Tomorrow I will be taking an Etheril trace (wireshark) to see for myself what the LAN network looks like under load and to also see if I can identify any networking issues that may be casuing the problem.
Mainly my reason for putting this up is to ask if anyone else recognises this issue or if anyone has any ideas how I can pinpoint the problem?
As usual both Redstone and BT just bat the ball back to me and after tomorrow I will be throwing it at Avaya with as much info as i can find to help them identify the source of this problem.
