Hi Ahmed,

Because the remote sites will have the phones registered to CME so in this case they will use the dial plan configured on respective CME.

Hi,

Edit: As mgogna  stated each site will need their own dial plan but if you are wanting dialling between branches you could try looking at using Service Advertisement Framework (SAF) which is often compared to a routing protocol for dial plan where the call control system advertises its own dial plan to other call control systems.

You can also use Call Manager Session Manager Edition which is a centralised aggregation for SIP trunks which can also provide more flexibility than the SAF

Just comes down to your requirements such as site to site dialling, least cost routing, etc

Hi heathrw

Thank you for your replay, what do i need to Make SAF network? it's Router having all these information ? is this feature same like making a gatekeeper ?

if we go to Call Manager Session Manager Edition, we can install it in one of the HQ UCS server ?

thanks again
