I have a Mitel 3000 system in my office with a voip broadband module and a remote ip phone at my home in another area code (long distance). I am not using sip trunks now (I had use of sip trunks for a year as part of the beta test for the broadband module). I have regular pots lines plugged into the system. So far the remote ip phone has been functioning flawlessley. I like being able make and receive calls as if I were actually in the office, as well as no long distance charges for incoming or outgoing calls within the office area code, when I am at my home during normal business hours. I like the design that the broadband module can be added to the "TDM" system as an option, if needed. I see potential for sales of the remote ip phone feature for customers who are away from the office or have remote workers. I have not had any customer requests for sip trunking.

With all the variables involved, I am amazed when any voice and data technology works like it is supposed to.
