Bangkok DID Number – Dual Channel SIP Trunk

Gain more trust from visitors when publishing a 02-BKK-Number on your website and business card. Receive more inquiries from your companies’ website when posting a 02-Bkk-Number in a prominent easy to find location. Instantly gain a better reputation as fixed line numbers are associated with a real “brick and mortar” business as opposed to mobile phone numbers that are considered to be “personal” by most people.

Digital and analog line phone numbers. What’s the difference?

Opposed to the fixed-line network where phone numbers are attached to physical cables that come into your office or home, DID or Direct Inward Dial numbers are digital lines that can be attached to your IP PBX or IP Phone and are connected via the Internet. When moving to a new office or home, simply plug your IP Phones to the Internet at the new location again, and callers can reach you instantly at your existing DID numbers.
