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. --- John Boteler BnC Group U.S.A.
