Question : Give access to trunk in Tixbox

I have an trixbox that act as my gateway between a Toshiba CIX 670 and a Cisco Call Manager Express.  I have the CME in my HK office with extension 5XX and my CIX is at my Corp office with extension 4XX, Swiss with 6XX connected to my CIX at the corp office.  Since I couldn't get the Toshiba and CME connected directly using SIP I put a trixbox in between.  The trixbox connect to the CME using SIP and to the CIX through 4 FXO ports. My HK office can call anyone on my Corp office and dial US cell/phone without a problem.  I cannot for the life of me get those FXO ports to be in the Internal context.  If I can get those FXO to go in the internal context that will allow my Corporate users (using the FXO ports) to dial users in my HK and Swiss office.  I have dial plans for all my sites.  Everything work great if my users uses DISA on the trixbox. I want them to be able to call directly once they hit the trixbox through the FXO ports.  BTW, the FXO trunk are group as g0.  I already tried editing the zapata.conf.  Keep in ming that extensions 5XX are reach through a trunk. I don't if that make a difference.  I know I'm overlooking something. Whenever I modified the zapata.conf to put the FXO in the internal context the fxo ports stop working.   Currently when you call the fxo ports from the Toshiba it goes to my IVR. I can then access all the services available from my IVR and all extensions on the trixbox, but I cannot access extensions that are accessible through trunks (ie. 5XX). My system is working and users are happy with it (I'm not), so I don't want to keep doing trial and error engineering any longer. :)

Please help. Any advice is appreciated it may lead me on the correct route.

Sorry, but there is no solution to this. It is not simply a matter of putting the FXO ports in the right context. It is a matter of FXO signalling which you seem to be ignoring despite my best efforts to explain the limitations to you. FXO ports do not receive the dialled number so you have no choice but to use DISA, Auto-Attendant or IVR. To do what you want you'll have to use a different technology - not FXO.
