Hi, I don't know if this is the correct mailing list for this question but I want to know that if I have 2 IP telephones connected to the same LAN and using an external SIP gatekeeper to make external calls, If I do an internal call. Do I use internet bandwidth during the whole call duartion or just in the registar time?
Sorry for my bad english, and thanks for your time.
