Hi all experts.
Our customer came up with requirement. They have 1 head office and 3 branches. All 3 branches are using CME. Headoffice has taken E1 from local telco. Now the requirement is,
When any person in any of 3 branches, dials 9 (access code), one of the E1 channels should be allocated to him !!! (if none are free, then he should hear busy tone)
Is this even possible ? how can a remote CME router can do that ?
