Hi,

I have submitted a new version (-23) of SIP Push.

As you can see, there has been a rather major re-write of the Proxy sections, in order to try to make the text easier to read and understand. Some features have been placed into dedicated subsections.

Another big change is that I have added procedures into bullet lists, based on Ekr’s comment that it was difficult to follow the procedures.

I have also introduced the “SIP Request Push Queue” concept, which is basically just a queue where a proxy places a SIP request that has triggered a push notification to the UA. Once the proxy receives the 2xx response to the REGISTER request triggered by the push notification, the proxy forwards the SIP request towards the UA and removes it from the queue. So, it’s not a technical addition.

I know that some of the figures spans multiple pages. I will try to fix that once the rest of the text is ok.

Regards,

Christer
