CME Problem with SIP-UA Credentials

Hi,
i have a little Problem with my Credentials in the sip-ua configuration. If i configure a username incoming calls working fine. But after some time (some minutes i think?) no incoming calls working. If i than delete the credentials and configure it new it works again for some time?
Is there a timeout issue? What do i have to configure?
Second question is -> How could i force a new registration to the SIP Provider? For the moment i look at "show sip-ua register status" the timer before i can debug the registration process.
Thanks and regards
Woisch

good luck... talk to your sip provider or go to their website, look under the technical details and find out how long the sessions stay active .. based of that info, adjust your register timers.
