I'm new to voice solution design. We are planning to set up Linksys IP Telephony at our office. After little investigation, i found I could use SPA8800 which can support analog phones and intergrate with IP network. I'm clear till this point. But am little confused on the end to end set up.
I want to use SPA8800 alone to connect my 4 analog phones and 4 PSTN lines and directly connect broadband to gateway.
I want to have similar set up in my remote office.
I want to make office to office calls via IP network while being able to use PSTN network.
(Branch A) Analog Phone ---> SPA8800 ---> [Internet] <---SPA8800 <---- Analog Phone (Branch B)
Does the above scneario work? Or do we need mandatorily need a system like SPA9000 in between to make IP calls?
You help is much appreciated.
