I have a customer that currently is using voice tool bypass between 12 branches and the headquarters. They have an ISR2821 on each branch and the headquarter, also there is a gatekeeper in the headquarter. There are no call managers yet.
They are evaluating the implementation of CUCM for the enterprise, they want start at one of the branch offices, adding a Call Manager, the PSTN gateway and the IP Phones.
They want to know what type of communication (link or trunk) can implement between the branch call manager and the gatekeeper at the headquarter ([email protected] office <-> [email protected]). Remember there will only one call manger at the branch office.
Im not sure about which type of trunk implement, h225 or gatekeeper controlled intercluster trunk?.
I appreciate any advice.
H.225 Trunk (Gatekeeper controlled).
Intercluster Trunks (ok or non-gk) are for going to another CCM or CCME.
You have to define a Gatekeeper object in CallManager first.
