4.3 Case II: Two-Site Configuration
This case describes the typical settings of a two-site configuration; say Company B headquarters
B-HQ and its branch B-BR in another country. Assume each site has a DSL connection for
Internet access. B-HQ has 4 PSTN subscriber lines and B-BR has 2 lines as shown in Figure 5-2.
The provisioning tasks include:
• Both sites have staff phones in cubes and offices and utility phones in public areas.
• Each phone has one extension. A utility phones can call extensions within the site it is
in only, while the staff phones can call any extension in both sites without limitation. B-
HQ has extensions 1XX and B-BR has extensions 2XX.
• Calls between B-HQ and B-BR use private SIP trunks across Internet. IP PBX at B-HQ
has a static IP address 64.1.0.1 and IP PBX at B-BR has a static IP address 222.44.0.1.
• Only staff phones can call out to PSTN with a prefix 9.
• B-HQ staff phones call out starting with 90118621 will relay to B-BR through the SIP
trunk and then hop off to PSTN in B-BR. Similarly, B-BR staff phones call out starting
with 9001408 will relay to B-HQ for PSTN hop-off.
• Incoming PSTN calls are answered by auto attendant and could be transferred to any
extension.
