Hello Voice-Ops, I have a frustrating situation where a random 1% of PolyCom phones (Mix, but all running 3.1.1) behind EdgeMarcs (VRRP 9.1.9) configuration are losing registrations overnight after a failed boot server check-in. (FTP) Phone will be URL call disabled until reboot or 12 hour+ wait. Inbound calls still work, outbound calls fail. Registration from a packet level is normal. Scenario is complex, but repeatable at multiple client sites. (so not firewall/lan) wireshark, tech support, release codes, ftp logs, and boot logs are all unhelpful/empty, and the firmware code (s) we're running can't be changed without proof, which at this point can only be generated by a fun weekend spent rebooting a cluster of phones over and over again, which for an annoying bug seems excessive. Bit of a rim-rock. Anyone seen anything like this? Cheers, Owen R. ____ Senior Network Engineer Impulse Advanced Communications 805-884-6332 owen at impulse.net
