Strange IPT Problem - 05/18/09 12:02 PM
I have a system that handles 2 businesses at 3 main locations. The original business has a couple of DKt's and a few off-site IPT's that work flawlessly. We recently upgraded the IPU to an MIPU, and kept the old BIPU since some of the IPT's are still the 1000 series that don't work with the MIPU. We added 6 5122-SD(site B) at one location and 3(site C) at another. Last Monday, site C had an issue where the IPT's automatically registered as the wrong ext number. So for instance, ext 3940 was reading as 3941, 3941 came up as 3942, and 3942 was reading a "REJECTED" error message presumably because 3941 was taking up the ext number. I went onsite and looked at the programming in the phone and all was fine. To correct the problem I had to unplug all phones and plug them in one at a time so that they could register as the ext that they were programmed to be.
On tuesday and then again on friday, the same thing happened to site B.
I have a ticket open with Toshiba tech support and have gone through a bunch of programming with them, and sent them a bunch of log files which they are reviewing now.
This is only happenening at site B and C and they are the only sites that have the 5000 series IPT's. Site A has a few IPT 2008's connected to the same MIPU and they have never had a problem in a few years. The only other thing that site B and C have in common other than the MIPU and the style of phones, is a small 8-port D-Link switch.
For the ISP, site B has a cable modem(Comcast) in front of the switch and site C has a DSL modem (Qwest).
My question is first off, has anybody seen anything like this or have any idea what the issue may be? Second question, could the D-Link switch somehow be causing this, and how? Finally, the third question, do you think this could be a bad batch of phones?
