<p>Jorj,<br>
The issue seems to be only with the Polycom UA making a call outbound. I can not find an issue with and inbound call. The Call-ID of the seize/appearance seems to be missing some characters on the prefix of the at-sign in relations to the real Call-ID of the INVITE/BYE. </p>

<p>Just my observation.</p>
