So, I have a company which is located on 2 sites. On Site A, there's one person who answers all the phones for the company (first-line), and does the finance and admin side of things. On Site B, there's 3 staff who work for the company doing 2nd and 3rd line support. The customers currently ring up a non-geographic number which is sent to the landline of Site A, where she fields the calls and would wish to pass a certain percentage of calls over to Site B for further resolution. Given that i'm going to use a mixture of one Patton gateway and a pair of Sipgate VoIP trunks, what is the most efficient design for the network? A) 3CX at Site A, Patton at Site A, Sipgate at both sites and 3 extensions at Site B all remote B) 3CX at Site B, Patton at Site B, Sipgate at both sites and the extension at Site A remote Also, is it best to assign the non-geographic number to the Patton or Sipgate trunk? Also (II), would it be best to have "PBX delivers audio" ticked for the remote Site A in scenario B above? Cheers, Mike.
