Hi Rahul, Sorry i wasnt probably clear enough. For the case when there are *no* proxies involved at all(configured seprately), and the calling UA is entered the address sip:[EMAIL PROTECTED] via a softphone GUI (where we assume joe is the computer name), how will the calling UA resolve the callee's IP?
I know that in case we have proxies then the UAC will pass INVITE to its local proxy (which as u mentioned is either configured or found) and that shall resolve the example.com (using NAPTR or SRV records) to find its SIP proxies. The message will be then sent to the proxy in example.com where the INVITE would be sent. The proxy in example.com can then find joe in its own domain and send the INVITE (or non-INVITE) request to the UAS. But what about the proxy-less case? can any body please explain that. regards Affan Ahmed --- Rahul Gulati <[EMAIL PROTECTED]> wrote: > Hi, Affan, > > The "example" here refers to the Proxy Server of UA which is > initiating a > call, > either the config file at initiating UA has the mapping for "example" > and > its ip address or it can be learnt through DHCP methods. > > Best Regards' > Rahul > > ----- Original Message ----- > From: "Affan Ahmed" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Monday, November 25, 2002 3:50 PM > Subject: [Sip-implementors] Peer to Peer Call > > > > Hello, > > I just wanted to clarify one point that dosent become clear to > *my* > > mind by simply reading the rfc.
