Experts,
We have CUCM V11. The call flow is simple one. Calls from customer to SIP VG then to CUCM extensions.
We noticed that when a customer calls the DID, the caller hears the ringtone and when that user transfers the call to another extension the caller hears the MOH and after that blank till the other user picks the call. The caller does not hear the ringing tone while transferring between extensions.
Can anyone share the thoughts on what things to be checked. I have checked the MRG and it has annunciator.
Thanks
Sathya
