Site 1 extension starts with 100 and site 2 extensions starts with 200 5. Users from either site should be able to dial local numbers from either locations using the PSTN lines      Eg. dialed numbers starting with 9 should dial out through one of 4 PSTN lines connected to US office system            dialed numbers starting with 8 should dial out through one of 4 PSTN lines connected to UK office system 6.

Cisco SPA8800 in each site as telephony gateway to provide 4 analog extension lines     ... View more
