I have 3 Quintum tenor AF with 4 FXS ports configured with public IPs at 3 diffrenet sites.
Quintum 1 is at the HQ to be connected to a PABX so that all HQ staff can reach the remote sites
Quintum 2 is at remote site connected to 4 telephones
Quintum 3 is at remote site connected to 4 telephones
I need configuration help to achieve the following:
1. Site to Site Dialing: so that users at any of the 3 sites can call one another.
2. Phone to phone (Extension) dialing within same location: so that user from one extension can reach other users on other extensions.
