I may have missed a thread search on here for this, forgive me if I have. I have 3 IP Office systems,406 V2, 1 in US and 2 in England. I can dial 3 digits between sites OK over my IP Trunks but what I am wanting to do is when I make a call to the UK from the US, I want to be able to go over the IP Trunk and dial out from their switch locally so as not to incur international charges. Has anyone set this up before?
