I am trying to figure out what the best way will be to transfer a call from one office to another. Here is the scenario, I have just been contracted by a company to provide tech support for them. Their office and mine if connteced via a broadband VPN connection and we both have two different phone systems (Lucent Partner and Nortstar/nortel). The take the phone calls in their office but they want to be able to transfer the call to my office so I do remote support. Any Ideas without spending a fortune?
