that depends entirely on how you build your gateway box, my gateway box ensures that all my customer calls remain on my network.

do you use as a gateway box?

Peter

asterisk 1.4.22

sorry, what i meant was what pbx manager do you use. Is it thirdlane single tenant?

thanks

Peter

Neither. Thirdlane dialplan is not compatible with CDR logging needed by billing software. Additionally the least cost routing engines I use, local number database, T.38 gateway software, and concurrent call count management, are all custom written applications to make my gateway asterisk box behave more like a phone switch and less like a PBX.

What's the problem with CDR logging? what is not compatible on thirdlane dialplan? and which dialplan is fully compatible?

asterisk logs based on source and destination numbers. a lot of PBX dialplans will fork a call generating 2 or 3 entries in CDR, or they re-write the destinations to extensions like 's' or the handset extension. How are you going to bill incomming toll-free if your destination keeps showing up as 212 in the CDR because that is where they pointed the destination to.

The CDR you bill with needs to be clean and absolute, 1 CDR entry per call, with a clear source and destination TN. Don't fork calls with a second Dial statement, dont use chan_local. Stick with Goto's and/or Gosub's.
