Hi, I am experimenting with VOIP with following goal: Build cost effective and reliable VOIP solution for a company with two branch offices (US and UK) with about 10 staffs each office. Other general requirement 1. For each sites 4 local PSTN lines are available to connect to the VOIP system 2. Each sites need about 12 extensions (8 VOIP/SIP phone and 4 analog phones as extensions) 3. Provide voice mail functionality for all extensions. 4. 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. Allow to connect to third party VOIP carrier to call any other countries (eg. numbers starting with 7 indicating to use the VOIP carrier to dial out) Please suggest how can I build solution for this. Can we use: 1. Cisco SPA9000 as central IP PBX in data center located in US. 2. Cisco SPA400 in each site as PSTN termination - 4 lines; which supports 16 voice mails 2. Cisco SPA8800 in each site as telephony gateway to provide 4 analog extension lines
