Fake SIP trunks for a Lab

[LoopyLou]

Not sure if anyone has posted on this before but looking for some options. I am building a lab to be able to test a MBG and MCD combo with SIP trunks. Mostly want to be able to work with Wireshark to be able to troubleshoot possible trunk issues. Have no access to real SIP trunks at this point.

What I would like to do is find some way of simulating a SIP trunk provider to the MBG. Was thinking of using a third party SIP PBX or even a spare CXi controller. Just a little unsure if it would work and if so what the programming would need to be for the MBG and the "fake" CO ( i.e the CXi ). Have reviewed some of the knowledge base articles for the various carriers. Not sure of the registration portion of the MBG SIP trunk setup.

MCD's both are R 5
MBG is R7

Any input would be appreciated. Thanks in advance.

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

think I used 3cx on a course once to simulate.

Could you try an Asterisk based distribution? Or are you after something different.

There is a KB article on SIP Trunking to Asterisk.

I use Elastix and it is easy enough to setup. You could virtualise it using vmware or vbox, call quality may not be good but you should at least be able to do some diagnositcs.
