Hi, <br><br>Right after we reboot the ISR and sip account is registered with the provider for the first time, all calls to the DID numbers are receivedby the auto attendant. After some time, when we call, the call does not come at all. checking sip registration shows the sip number being registered. Is this any keepalive or any ports/registration issue ? how do I troubleshoot this issue? ccapi inout does not show any attempt of the incoming call at all. Provider says its all OK in their end and see our sip account registered. I am using Cisco Unity Express Version 7.2 / Cisco Unified IVR Express<br>
<br>Thanks,<br>Sam<br>
