Cannot Connect SIP Softphone to CME 8.6

Hello all....I'm having trouble connecting a 3CX SIP softphone (Windows) to my CME router- version 8.6. Router is 2851 ISR- all connected via a lan switch in my office. Connectivity is fine between the PC\softphone and the router.

I have successfully setup 3 SCCP phones (all Cisco) but I'm not too clear why the SIP softphone is having issues- I've Google and read quite a bit but maybe somebody can check my config-- I'm sure I'm missing something. Also, tried to get some debug info from various debug ccsip xxx commands, but the console is overwhelmed with lines of debug- nothing that stands out anyway. I am familiar configuring sip phones for Asterisk....as I have a working PBX up here...but not so much for CME\Cisco.

Here's my pertinent config sections---  like I mentioned, I have working skinny phones on the same CME system. I wouldn't need to specify phone loads and type and tftp paths for a simple sip softphone would I???     Thanks in advance....Dennis

Nadeem-- thanks-- nice outlined config in the blog! The main thing I missed was the registrar itself no being "turned on"!

sip

registrar server expires max 600 min 60    turns on the SIP registrar!

It became blatently evident when I issued a debug ccsip events and got this:

CCSIP_REGISTER:: Registrar is not enabled

Lesson learned- thanks again

Dennis
