[Voxalot / SIP Broker Support Forums] Problem calling another Voxalot - Voxalot / SIP Broker Support Forums: is a feature that can be activated only when there is a fault that causes a non-routable LAN IP address to be used as the Contact Address in a SIP SDP packet. This can happen when the ATA is behind a symmetric NAT router, the ATA is mis-configured, or a STUN server is not working, etc.
[Internet Drafts: sip] draft-ietf-sip-199-08 - Response Code for Indication of Terminated ...: Since all SIP entities involved in a session setup do not necessarily support the specific meaning of the 199 Early Dialog Terminated provisional response, the sender of the response MUST be prepared to receive SIP requests and responses associated with the dialog for which the 199 response was sent (a proxy can receive SIP messages from either direction). If such request is received by a UA, it MUST act in the same way as if it had received the request after sending the final non-2xx response to the INVITE, as specified in [RFC3261].
[TechNet Blogs] Microsoft UK UC Blog : Reverse Number Lookup and Dealing with ...: When the invite message is received by the Office Communicator client it uses either the “From” field or the “P-Asserted-Identity” field to match against the address book and local Outlook contacts. The problem here is that the numbers in the address book come from Active Directory and these are usually in the short dial format as they are used by users who are not using OCS enterprise voice.

[Dialogic Exchange Network] Brand new to SIP, DMG 1000 and entire VoIP - very overwhelmed and ...: What we need to do is eventually configure a normal PSTN telephone number somewhere in our PC software (that we will have to write for ourselves, a client side application) and then have our PC software call this number, which presumably will talk SIP to the DMG, and then the DMG will dial out and communicate through the PSTN. I sure hope that I have that flow figured out at least, but like I said, I'm in acroymn overload.
[Mu Dynamics Research Labs] Mu Dynamics Research Labs » Blog Archive » D/DoS Testing Network ...: If you look at the SIP INVITE message there are a number of regions within the payload that either need to be randomized or need to be tied to the L2/L3/L4 header values. In other words if we are generating random IP addresses and/or ports for each packet, then the payload needs to reflect that to make the server think it’s unique and valid.

To that point, the person creating the “network” starts off with full administrative powers and can also give others administration privileges.
[Jan Luehe's Blog] Jan Luehe's Blog : Weblog: This blog explains the motivation behind a converged application, provides a step-by-step analysis of how a ConvergedHttpSession may be used to initiate and terminate a SIP call from the HTTP servlet of a converged application, explains how the routing decisions of SailFin's Converged Loadbalancer influence the session id of a SipApplicationSession created from a ConvergedHttpSession, and finally shows how a ConvergedHttpSession fits into SailFin's in-memory replication framework that provides high-availability of HTTP and SIP artifacts in a SailFin cluster.
