<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">RFC 3261 section 16.7, bullet point 2 states:
"...if the response is a provisional response with status codes 101 to 199 inclusive (i.e., anything but 100), the proxy MUST reset timer C..."
This else case needs to be modified to not execute if the response is a 100.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think I agree with Mark here as well, and the RFC makes sense when it says to not reset Timer C on a 100. There's no real need to reset Timer C in that case, as that typically comes directly on the heels of the transmitted INVITE request.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">SIP Timer C is defined for proxys that forward messages. In some ways, we forward calls. It is activated when we receive a 100 trying and wait for any other message. If that's not received, timer C triggers and cancels the call attempt.
This is required in an interoperability test I'm working with.
Red dots will be handled in the way they deserve.</pre>
