Thailand SIP Peer  Trunk Virtual E1 Line

With VoIP Thailand, you can get SIP Peer Trunks from all over Thailand (Bangkok, Chiang Mai, Hua Hin, Phuket, etc.)! One SIP Peer Trunk supports up to 30 simultaneous calls. Choose your Virtual E1 line with 30 or 100 attached phone numbers.

SIP Peer Trunks require a fixed IP Address and are compatible with most phone systems. If you decide to go with a hosted IP PBX from VoIP Thailand, you will automatically receive your own dedicated fixed IP Address with our Cloud PBX Setup.

Typical applications for SIP Peer Trunks are:

  • Offices with more than 25 extensions
  • Call Centers

Thailand E1 SIP Peer Trunk vs. Thailand E1 PRI-ISDN Trunk. What’s the difference?

VoIP Thailand’s E1 SIP Peer Trunks register via the Internet to your IP PBX in the Cloud or On-Premise. You require a fixed IP Address to register the phone line in your PBX. No physical installation or wiring is needed.

VoIP Thailand’s E1 PRI-ISDN lines require a physical installation at your office location. For this reason, you have to pay additional installation charges for these lines. E1 PRI lines need a physical E1 voice gateway that allows connectivity to your PBX. The Audio signal is transported via a separate phone line, and your phone system will also work if you don’t have any Internet connectivity.

When moving to a new office location, the line can not easily be moved but requires complete new wiring. If you move to another district, you might also lose your current phone numbers.
