Question : Trunking 3com VCX connect 100 to trixbox

Hey experts,
So here is the situation i got, we have a VCX connect 100 that we are trying to link to a trixbox system.  I have looked all over the internet trying to find any kind of help with this as 3com doesn't off anything of the such.  I have added the Trixbox as a trusted endpoint in the VCX but i believe my issue lies at the trixbox as i don't know the parameters to put in for trunk.  
Anyone have experience and can offer some help with this?

You tried plain SIP trunk parameters to get it working?
