What is SIP Trunking?

SIP Trunking from KOMPaaS is a service for establishing a virtual communication line (trunk) between your company's telephone equipment and our Virtual PBX.

With the help of SIP Trunking you can easily add and remove telephone channels, unite your company's office and mobile phones by assigning short internal numbers to each user, and reduce communication costs due to lower long-distance rates and free calls within your company's phone network.

What is required for SIP Trunking?

  • Stable and Fast Internet Connection

    SIP trunks work best over a dedicated fiber optic line with a minimum speed of 65 kbps, so please consider measuring Internet speed before setup. We also recommend you take the time to configure QoS.

  • SIP-enabled phone system

    If your PBX doesn't support SIP protocol, in most cases VoIP gateway will enable connection to our Virtual PBX. If you have any questions about virtual trunk installation, we are ready to provide you with all necessary technical support.

How does SIP Trunking work?

It all comes down to connecting the client's various telephone equipment, traditional or digital, to the provider's server that enables VoIP calls to any phone networks.

Digitized voice travels not through copper loops or ISDN cables, but in a virtual environment, so one doesn't need hardwired connections to organize an effective business telephony.

Moreover, packet-switching VoIP telephony, if set up and managed correctly, provides a signal quality comparable to traditional circuit switching technology.
