Hi there, I am stuck with the location issues. It would be easy if you have DID for each extension so that outgoing caller id would be DID of the respective extension and also physical address. Now if you are not able to get DID's for some reason. I am thinking of some situations and appreciate your thoughts. 1. If I have a PRI and map physical number (original numbers in hunt group not the group number) to some extensions. If somebody calls emergency from a specific location in a building either it will have outgoing caller ID of that specific number in PRI group (if possible) or always dial that physical line which has address of that location in Telco database. Is it possible? Can we have different caller ID's for a PRI? I mean my PRi has one number 12345667 known to outside world. But it has 23 physical number in original.Please comment 2.If I have analog lines, incoming call can use any channel and out going calls from any extension can use any channel. If somebody dials emergency then that specific extension dials specific channel which has its physical location in Telco database. I would highly appreciate your thoughts.
