We have recently upgraded an IP 403 on a customer site from Version 1.3 to 3.0 with all of the intermediatry steps. In addition to the main unit there were a couple of extension units with 16 Analaog Ports, 8 Analog Ports and 8 Digital ports. These all upgraded ok.
We performed some work after the upgrade messing arond with hunt groups etc but nothing too drastic.
Having left the customer site we were told this morning that a number of extensions can not recieve internal calls. If you ring them internally the phone just goes dead. These extensions can make and recieve external calls directly and make internal calls but not recieve them.
I have checked all of the configuration and can't see any obvious reason as to why this should be happening.
Anyone have any ideas/advice?
