You can hit redial and the call will complete just fine. Telco switch is a DMS100 running ni2. My equipment is a 2951 with a VWIC2-2MFT-T1/E1. IOS c2951-universalk9-mz.SPA.150-1.M2.bin</div>
<div><br></div><div>I have a colleague with a similar issue who swapped his 2951 out with a 2811 and that cleared up all problems. Is there something with the 2951 that is causing this problem? We are not having any luck with them. I have not tried swapping this one out yet.</div>
