Please can you help me to make a good Translation rule in my issue
Office A has extension : 15.. (1570,1571,1572....) in Mainz external telefon is 06131 74....
Office B Has extension : 25.. (2501,2502,2505,....) in Frankfurt external telefon is 069 69....
connection between A and B over Wan and PSTN
for the dial Peer over Wan i don't have any Problem
but I need to make a Translation Rules that if the Office A need to make Phone make that from Frankfurt PSTN not from Mainz
Mean all Phone go to Frankfurt any customer should see only frankfurt number or office B not A (TEHO) system
office A should use the Mainz PSTN if WAN has failed
all telefon should from A to B over WAN
