We have two Cisco Call Manager(Publisher & Subscriber). All the phones associated with subscriber are working fine no problems. Some of the phones that are associated to Publisher they are not registering with it. I don't know what is wrong with this. I restarted both Publisher and subscriber. Restared tftp server. We are running call manager 5.0. Most of these phones are 7911. I did change their version from SCCP11.8-3-2S to SCCP11.8-3-4S cause the time was 1 hour ahead this solved the problem. After few days they stop working and when I changed one of the phone back to it's old firmware it started working but again time is 1 hour ahead of normal. Can any one help me in this please? Thanks.
when you say ( Some of the Phones that are associated to publisher they are not registering with it )
do you mean they go to register with the subscriber or they just circuling around like crazy ??
you may need to check the cisco call manager groups in you ccm
make one group for registering with the subscriber
make another group to register with the publisher
configure these groups in your device pools - to select which register with pub or sub
i think this might help the issue
let me know what happen ... ok
Thanks Uday for your reply...
In our office we have two buildings phones in one building belong to Publisher and phones in other building belong to Subscriber. There are mostly 7911 phones in Publisher are not working. When you power on the phone it says Upgradding........and the says error. After this it does not do any thing. When I took the phones to other building and connect it to the port there it did the firmware upgrade and then got registered to Publisher. In the end i tool the phone back to the old place and it starts working. I don't understand why could be the issue? I also installed the firmware in call manager Publisher for 7911. SCCP11.8-3-2S restarted the tftp no use.. ny ideas bout this?? Thanks.
1- check the firmware version on both ( pub + sub ) are the exactly match ????
be very carefull about every thing in this the 7911 has nine files for it's complete firmware
2- check the dhcp in the first building ( what tftp ip it give to the phones ) ?
i'll keep checking the page when i can for your responce
