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.

Javier,
just the signalling goes to the external SIP registrar/Proxy. The RTP (voic) traffic will only go across your lan segment.

If both phones and SIP proxy have public ip addresses you will only send signaling traffic to the proxy.
If some of the elements is behind nat, all traffic (both signaling and media) will be sent to the proxy. Note that you will need some kind of RTP proxy if you want that natted device is able to receive calls.
