VOIP Phones re-registering after v6.3 to 7.x upgrade
Running CallManager 3.3 at HQ facility with 3 remote sites that register phones via IPSEC tunnels to HQ. Recently tried upgrading my HQ Pix 515 from 6.3(3) to 7.0(1) and it caused the phones to start reregistering sporadically at only the remote sites. HQ phones were ok. Any ideas?
