I have a Cisco UC 540 and we are registering SPA504 and SPA525 phones on the CCME side. We also have a few Cisco WIP320 phones.<br><br>I have the WIP320 phones registered via SIP, but calls to the SPA phones are having serious audio setup problems (no audio, one way audio, sometimes two-way audio....)<br>
<br>The calls are G711U all the way thru...<br><br>Any ideas on what else we should check?<br><br><br><br>Jonathan<br>
