Question : TEHO implementation

Hi there,

I'm trying to get an understanding on how to implement TEHO for free long distance. So basically what we're doing is this:

1. Use an Analog phone connected to FXS port on a 2621 XM router ?

2. Get a public I.P on this router and configure it with voip dial peer whose session target will be (Next step) and have correct voice-translation rule applied on that VOIP dial-peer so that caller-id is routable by PSTN ?

3. Get another router (e.g. 2621 XM) in Country B whose Public I.P will be the session target on the voip dial-peer of Country A router.

Note: Since both are publicaly routable I.P's, session-target should work as per my understanding ? I can still form an IPSEC tunnel between the two and make it work.  

4. Country B router will have a PSTN connection (via FXO port) to the local PSTN there.

5. Create a dial-peer on Country B router to route the call with incoming called number (which would be dest-pattern .T i.e. any number) out to the local PSTN using its FXO port. Do I need to create a translation rule on this router ?

I'm just interested in knowing the technical answer as I just want to understand what TEHO is and how it works and not get onto the legal side/advise of things as I know it's illegal !

Answer : TEHO implementation

Well I think I may have resolved this myself.

I put in a sortCompareFunction called from DataGridColumn and then I put in a dummy field into the Model class. So when the Sort.as still went and checked the dataField it found the field and did not spit out the error. Directly after that the sortCompareFunction then gets called and does the actual sort. Not very pretty but it seems to work now.
