I have a Telrad system in the UK and have a VOIP link to my office in Spain - e.g. we have a VOIP phone in Spain that connects to the PBX in the UK to dial out / receive calls. The data is carried over a secure VPN.
Does anyone know if it is possible to connect FreePBX (or any other variation) to my Telrad system ?
I would like to run more than one phone in Spain and thought it might be a way to go…
Failing that, are there any open source soft phones that would connect ? I can get the exchange in the UK reprogrammed for extra lines / extensions if need be.
Any suggestions gratefully received.
