<div>We saw this happening a number of times and found it was coincident with a DHCP lease expiration period. Running Ethereal traces on the phones confirmed that it reset after a DHCP interaction, and hard coding the IP address was the workaround. You could try that while waiting for a solution or better explanation.

<div>You could also try moving the phone or switch port to another network to see the behavior is specific to an underprovisioned network.</div>

<br>switch fast ethernet.<br>The phone also sometimes gets registered on the SRST which is on the<br>same site. it gets unregistered at the same moment and gets registered<br>back to the CCM.<br>It gets power seperately from a power cube (2950 has no POE)
<br>Even if it gets registered on the SRST and back there is no reason for a<br>full reset.<br>Because it has one 7914, it is very noticeable since all lights start<br>blinking!<br><br>I took a trace from CCM service but nothing came out.
<br>What are most common reasons for reset of a phone?<br>An other 7970 with 7914 also does the same. The customer has not noticed<br>if other phones do the same thing but those 7970 do it for sure.<br>Could 7914 be the problem?
<br>7914 has S00105000200 image.<br><br>Thanks<br>Anthony<br></blockquote>
