Transfer to UCD on HiPath 3800

[telbisjon]

Hi
I have a 3800 which is dropping calls to a UCD group from the reception phones. There are 3 UCD groups in use & no problems with the other two. All agents are logged on & most are idle when this occurs. Reception do a blind transfer to a number pointed at the UCD group & this has worked well for quite some time. I have had the provider check his PRI & they say no issue. Calls are only dropped when transferring from either reception phone to this UCD group 441 to#202. This has been happening quite often in the last week & only change to system has been a HG1500 card so that should not effect anything.
Any ideas guys?

Did all the parameters stay the same when you replaced the HF1500 card? Sounds like it could be a setting like supervision or something.

Thanks for replying donb01 but have checked settings & see no changes. It is dropping at the rate of 5% of calls so is definitely a fault of some type. Am a bit reluctant to remote onto kit as last time the switch rebooted for some reason. Seems to be a bit unstable so will cobble together a replacement just in case.

Update, Customer still losing calls but says calls hit UCD then ring 6 times before going to MOH source which is analogue extension. They hear the MOH & get recall back to MOH then say they are cut off. I know their are no limits on MOH channels but am wondering if at some stage the MOH is failing giving dead air. Customer on not hearing anything hangs up. Just a thought

Does the UCD group with the problems have the same overflow and timer settings as the other two groups that are not having problems?

Hi donb01, Yes exactly the same overflow & timer settings
