Thailand DID Number with concurrent calls - VoIP 

Thailand DID Number with  concurrent calls - VoIP 

With VoIP Thailand you can get DID numbers from all over Thailand (Bangkok, Chiang Mai, Hua Hin, Phuket etc)! Perfect for Call Centers & Businesses.

DID works similarly for VoIP communications. To allow PSTN users to directly reach VoIP users, DID numbers are assigned to a gateway. The gateway connects the PSTN (public switched telephone network) to the VoIP network, routing and translating calls between the two networks for the VoIP user. Calls from the PSTN will be directed to the VoIP user who holds the corresponding DID number.

DID Numbers requires that you purchase an ISDN or Digital line and ask the telephone company to assign a range of numbers. You will then need DID capable equipment at your premises which consists of BRI, E1 or T1 cards or Gateways.
