This sounds very much like what happens when you have a transit
network device doing packet/protocol inspection that does not
understand the messaging associated with those features. Is there a
NAT boundary, firewall doing inspection, or similar network device
between this phone and the CM server? Can you move the phone closer
to the server to confirm it is not a network issue?<br>

I've got a 7962 with one 7915 expansion module. When I change the
phone button template on the phone to include BLFs, the phone
deregisters and goes into SRST mode. I also lose Line 1 on the
phone. The phone resgisters when the default phone button template
is used. I'm using the lastest firmware for the phone and the
expansion module. Has anyone encountered a similar problem.<br>
<br>
Kind regards,<br>
<br>
