8831 Unusually Long Registering Time?

[art.lacie]

I have 8831s that I lend out on request. The first time I put these phones out to use they worked great - basically that was to test the phones and the jacks they would be connected to. 

Lately it seems that the phones take forever to register. From the time I plug it in until it's ready to go, is at least 10mins. Before, it only took 2 minutes to register. Any ideas what's happening here?

Hi,

Please answer the following questions:

1. Are you using these phones with CME or CUCM?

2. How many phones have you tested and how many are slow in registering?

3. can you try upgrading a couple of 8831's to the latest load 10.3.1(SR3) and compare the results?

Thanks for responding:

1. CUCM

2. 20 phones in inventory. All of them were tested last winter, and worked as expected. They don't get used often. Some of them that weren't used since last winter, seem to activate/register between 2-5mins. Ones used a month ago, seem to either not register, or take at least 10minutes.

3. Can definitely try 10.3.1
