Retaking this thread I would like to comment my progress with this process
I had to disable account codes since they were UNCOMPATIBLE with $KEY and trunk to trunk connections, if I used the 80 ARS, call would not be done.
Only alternative I had to overcome the “80” line problem was cloning this line, but deactivate all (yes – all) the “force account code” checkboxes.
A group of users (remote location) are able to call dialling “82” (80’s clone) and they are the only people supposed to be aware of that, but of course, if any other user inside or outside the company uses the “82” will able to establish un-restricted codes.
We have an ISDN, 4 mobile gateways, 4 Voip Direct numbers, and 4 data channels with a remote location via Cisco Routers.
Virtually all the combinations of trunk to trunk calls are enabled.
My customer is aware of consequences of the –almost unrestricted- trunk to trunk connections, he wants to cut costs of telephony biding every user to use the collective phone resource.
Even more, because the only alternative
One of you said that its not the “best practice” and that’s right, as far as these secrets can’t be keep as that for a long time.
The trunk to trunk international, mobile or any kind of calls can’t be tracked
There’s a system for accounting and billing running on a PC taking CDRs from the IP 500, via 8090 port. The system detects account codes (on purpose authorization codes show as passwords ******, so could not be used for auditing user calls), any call made trunk to trunk is not tracked, not registered, not billed.
FINDING A DEFINITIVE SOLUTION
I told the customer that we could use some methods to prevent illegal access.
1) personal shortcodes, the user will have a *something* shortcode that will lead him to a individual module on the VMpro (paper says it has unlimited modules) this module will be PIN protected, and only the user will know the PIN, later, when call is established the accounting software will see “calling from jon_jones_attendant”
2) a way that user validates himself when making a call from outside. Curiously the customer is familiar with Altigen and Nortel and said it was possible to do on those old machines
You have mentioned that 4.2 release will do more on that, can I keep the hope?.
3) Trying other features of Voicemail (we have the 4.0.20 release) that help to make a more secure trunk to trunk transfer.
