My understanding is that SIP works point to point, regardless of having a STUN server or not.

The purpose of having a STUN server is to traverse a NAT enabled network. If you have a private address behind a NAT device, then you may have to use a STUN server -- otherwise it is not necessary.

[STUN is secure traversal of UDP packets over NAT].
