We've been using pbxes for several months to run a virtual office where 3 of us are in remote locations and can transfer calls between us etc.
We are now taking the plunge and moving into an office, what is the best way to set this up with pbxes.org? Is it worth getting a DrayTek style router that has VOIP built in and using it as a sub pbx? How can we best save bandwidth internally between calls yet also have the option to use extensions remotely?
