point out if anything out of above is not correct or if people can add
more?<br>
<br>
I'm not sure which criteria you have used, but the ones you use do not
differentiate between a full-fledged SIP proxy and a SIP stack. I
would assume that an important criteria would be comparing the code
base for each to find the needed delta for implementing what you are
looking for.<br>
SER is NOT a SIP stack, it is a SIP proxy server you can easily extend
with ser.cfg and your own modules. <br>
<br>
To the GPL: You can commit your code in GPL, but retain the copyright.
This holds for modules, as well as independent code files in the core
(however, getting your code into the core takes more...). With the
copyright, only you can modify/extend your code for a commercial
version without publishing the commercial modification.<br>
<br>

actively being used for IMS enhancements?<br>
<br>
I don't know, most IMS enhancements are below the radar. If you are
looking for a stack, reSIPprocate is known as the most mature stack
used in many commercial projects. If you are looking for a server, I'm
sure SER cannot be beaten on the modular extendability and especially
the configuration language in ser.cfg.<br>
Tekelec has a commercial IMS server with SIP core as a basis, and at
least one other person on the list has very recently started to look at
CSCF module development.<br>
<br>

near future SER release with IMS support (CSCF mainly)?</span></font><br>

Only
4-5 days ago, there was a thread where Dragos documented the work done
at FOKUS and which modules/functionality that FOKUS will soon make
available (GPL, I think).<br>
