Keep-Alive Timeout for Expressway Connected Phones

[ybpants]

I have some 8861 phones connecting to the enterprise via Expressway and it works great (a big improvement on VPN phone).

Although everything is working i was just wondering if anyone knows the keep-alive timeout value before the phone will unregister?  I am sure that this is out there somewhere but i could not find it.

thanks

Hi ybpants, did you find a solution to this? I am seeing the same issue with remote 8841s dropping their connection to Expressway after 12-24 hours.

I upgrade the firmware for the 8861s to SIP88xx.11-7-1-17 and the difference was night and day.  Since the upgrade all users on the expressway connected phones (except those on FiOS but that is another story) have reported a major improvement with connectivity.
