SIP/2.0 503 Service Unavailable Intermittent

Hello!

On the latest iPhone client is anyone getting intermittent Jabber connectivity to CUCM? Didn't have this problem until updating to the latest Jabber client. One connection works, but if you attempt it later it may not work... All other components (directory, voicemail) connect OK...

here is a snippet from the iphone debug logs.. any insight appreciated. CUCM v8.0.3. thanks!!!
