You do NOT have to purchase a SIP trunk for each DID number you have, in fact, you can have multiple DID numbers (Can be from different countries) and use them all under one SIP trunk.

You just have to purchase the numbers from our number partner Hoiio, provision all your numbers under your existing SIP trunk.
