All IP telephones are registered with Publisher and only two telephones are registered with Subscriber.
The two telephones which are registered with Subscriber got a very strange issue. When I try to retrieve a telephone number from Directory, it takes ages to show up. It's very very slow. I did the following steps but it didn't help:
1) Reset the phones
2) Delete the phones and inserted once again
3) Checked the switch ports on which the phones are connected
4) Restarted Cisco Tomact service
I hope someone can help me to reslove this issue. How I can force these two telephones to register with Publisher.
