has any one used voipfone as a "trunk" provider, rather than the vpbx solution?
i am going to suggest the avaya quick edition solution for a small business user, but need to know how DDI's will work
one method would be to purchase extensions, create a vpbx and then map these extension to actual phone extensions in the Avaya system, but this seems a little long winded.
if i purchased a bunch of ddi's in one account, with no extensions, do voipfone send the DDI number across? is there any special type of signalling i need to make sure the Avaya system can understand to ensure it will route the inbound call to the right extension?
any guidance would be appreciated.
