Phone constanly re-registering

[nitterhouse]

What would cause several phones to constantly keep re-registering about every 5 - 10 seconds? This is occuring on multiple extensions (not all) on two different servers. Here is an example of the logs:

12:28:02.468 ExtnCfg::updateContact [CM504002]: Ext.303: a contact is unregistered. Contact(s): []
12:28:01.750 ExtnCfg::updateContact [CM504001]: Ext.303: new contact is registered. Contact(s): [sip:[email protected]:5060/303]
12:27:57.828 ExtnCfg::updateContact [CM504002]: Ext.303: a contact is unregistered. Contact(s): []

The phones are UTStarcom F1000G WIFI. The phones are not losing wireless communication during this period.

Thanks.

Set your phone's "Register Expiration" to longer time. Normally, the default value is 3600 sec.
