PLACING CALLS THROUGH A TRUNK
There are three ways to make a call using a trunk:
- Using System Default Trunks
- Navigate to 'System: Default Trunks'
- Set 'Primary Trunk'='System2'
- Click 'Save'
- Any 'Proper/Mobile' number dialed on the system will go through 'System2' trunk
- Using 'Extension Default Trunks'
- Navigate to 'Extensions: Edit: Advanced Options'
- Set 'Primary Trunk'='System2'
- Click 'Save'
- Any 'Proper/Mobile' number dialed by the edited extension will go through 'System2' trunk
- Using 'Other Network Prefix'
- Navigate to 'System: Servers: Edit: Other Networks'
- Set 'Mode'='With Access Code'
- Click 'Save'
- Click 'Add Network'
- Set 'Name'='System2'
- Set 'Prefix'='8'
- Select 'Trunk'='System2'
- Click 'Save'
- Any 'Proper/Mobile' number dialed on the system will go through 'System2' trunk
To place a call through the 'Other Network' with the above settings, dial *188 + 8 +$System2EXTENSION (e.g. *18881005) where 1005 is an extension on System2
To enable calls from System2 to System1, just reverse the above settings (create a trunk on System2 and Extension on System1).
