4.1.3 Upgrade to 6.1.2 CUCM Experiences Delay when calling between IP Phone

Hi Techies,

We have recently upgraded our CCM 4.1.3 to CUCM 6.1.2 and everything works fine except the below.

Scenario 1

We add 2 new IP Phones to the CUCM6.1.2 Cluster and place a call between them, there is 2 to 3 seconds delay in placing the calls between these 2 new extensions.

Scenario2

We call from the newly added IP Phone to an extension that was there in the Database that was imported to CUCM 6.1.2, there is 2 to 3 seconds delay in placing the call.

Scenario3

We place the call between the extensions that were there in the CCM 4.1.3 Database that was imported to CUCM 6.1.2, the calls are fine.

We have verified the DB Replication Status between the cluster member, the speed, duplex settings on the Cluster and the IP Phones, they are all fine.

It is a very weired problem and any inputs will help in resolving is highly appreciated.

Regards,

Sriharshaa Prabhakar
