<p>Ryan -</p>
<p> Thanks for the response.</p>
<p> </p>
<p> To be more specific:</p>
<p> </p>
<p> From Cluster 1, I pick up a handset and dial 5100. That is a phone registered to the CUCME. Nothing happens. No progress tones, no drops. Just dead air. 5100 never rings. Almost like it was waiting for interdigit timeout.</p>
<p> </p>
<p> Replace the handset and then dial 5101 (another phone registered to the CUCME). Same thing.</p>
<p> </p>
<p> However, from the CUCME, phone 5100, I can place a call to the Cluster 1 handset. I can also place the call from the 5101 handset.</p>
<p> </p>
<p> Repeat the procedure for Cluster 2 with the exact same results both ways.</p>
<p> </p>
<p> </p>

<div>Can you be more specific in how the calls fail? Do they complete (both phones ring, answer and go to connected state) but you get no audio or does the call not complete or just drop?
<div><br>
</div>
<div>Audio issues are not typically related to call signaling unless the call drops to reorder after ~15 seconds. They are more commonly simple routing issues between endpoints.</div>
