I had that with some Poly(com) VVX501 phones.

The solution was to set every occurrence of .regevent="0" so reg.1.regevent=”0”, reg.2.regevent=”0”, and so on.

From their docs:

voIpProt.SIP.regevent

0 (default) - The phone is not subscribed to registration state change notifications for all phone lines.
1 - The phone is subscribed to registration state change notifications for all phone lines.

This parameter is overridden by the per-phone parameter reg.x.regevent.

I did not troubleshoot it, I simply set it to 0 and moved on. I have no idea what the equivalent would be on a Cisco phone, but if you see a related setting maybe it’s worth toggling it to see what the result is.

Hope this helps.
