Thanks David44 and Cerien.Jean.
My VOIP expertise is a little less than nil. Although, when our office went to VOIP and I was given the option of having an office extension in my home office (150 miles from my official workplace), it was I that figured out how to get it working. Mostly trial and error but based on some advice I found on the Internet that ports 5060-5070 (depending on the number of lines required) needed to be forwarded to the VOIP phone and some high number ports needed to be open.
Learning to manage an asterisk server is not high on the list of things I want to do. I was just seeing it as a possible solution. However, after the bafflegab I got from my ISP tech support, who simply said that it could not be done but could not explain why, and the company that installed our office system, it is apparent that Internet telephony management is not for the faint of heart.
Am I understanding correctly that it is actually the VOIP phone that defines the port that it is to be contacted on? If that is correct, then there should be no real limit to the number of different systems working on one Internet connection. Mine is dynamic DSL, if that makes a difference, and I have a DynDNS with my own host name.
I am thinking that the best route might be to take my ISP up on their trial VOIP offer and see what it takes to make things work.
Best regards,
Dennis
