I have a BCM 400 4.0 just converted to VOIP for IP telephony sets. Currently 3/5 spilt with 4 PEC III cards. Every now and then they puch the intercom button on their 1120e sets and receive try again later. Set is online, not off line and still registered to the BCM 400. Has anyone had this same issue with any BCM level unit? Patched to 4/30/09 for patches with a CISCO 3560 for the network and no data all dedicated VOIP!
