Hi All,
When we call somebody or receive a call (all calls internal and external) than the first 1-2 seconds are quiet and we or the other person does not hear the salutation i.e. "Hello"
Please let me know the cause of such issue.
Thanks

Because delay dialtone points to a QoS problem.
Something change on the network, like configuration or ISP side they make any changes?
Other thing what is the RTT between the IP Phones and the CUCM?
Thanks
