could anyone clear this up for me please:
VPN our GRE tunnel?
if we wanted to have an asterisk multisite, with one *box in France and the other in Poland, what would be the pros and cons setting it up as a VPN tunnel our GRE tunnel?
DISA billing with multisite
let’s say someone of the office in Poland does a DISA with GSM or landline to the Poland *box in order to phone a french GSM or landline. The call is transferred to the french *box and “gatewayed” to the french PSTN or GSM operator. Now who pays what?
Let’s say it’s a GSM > GSM call.
The caller should logically pay:
a Polish GSM > landline call (to polish * box)
a French landline > GSM call (from french * box)
is that correct or do i oversee something? The French agency with the *box doesn’t pay a dime right?
Now surely i guess it’s technically possible to do a DISA directly to the french *box, but i guess that this would have no interest as it would be considered as a reguler Polish GSM > French landline call?
Does anyone have experience preferring doing a DID call with local polish number to the french * box? Would that be any cheaper than a DISA call to the polish * box as discribed?
