SIP Trunking and Secure Cloud Communications Work Together

You can include SIP trunking in your secure cloud communications solution to reduce costs, minimize your investment, and get access to real-time communication services.

Businesses benefit from the powerful real-time communications capabilities offered with SIP trunking, and at the same time enjoy low-cost feature-rich VoIP quality calling.

SIP Trunking

A SIP trunk can connect your company‚Äôs SIP-enabled devices, including IP phones or your existing IP-PBX. You won’t need gateways to convert TDM traffic to VoIP.

SIP Trunking Provides Cloud Communications Access at Lower Cost

SIP trunking is the protocol of choice for telephony, conferencing and other communications sessions on the Internet. SIP combines voice and data on a single broadband circuit.

With SIP, you can connect an existing PBX through a SIP trunking provider like AVOXI to the PSTN (public switched telephone network).

This means that, instead of using a trunk provided by your existing telecommunications carrier to carry away all your phone traffic, you can use a SIP trunk.

SIP has a number of benefits that make it an attractive solution for cloud communications.

  • Lowers connection costs as your calls pass through the Internet
  • Highly scalable – Configured online and provisioned from existing capacity
  • Can connect to existing legacy equipment like on-premise PBX equipment
  • Excellent voice quality audio through VoIP
  • Encryption via Transport Layer Security (TLS) provides en-route security
  • Enables companies with legacy PBX equipment to use real-time communications
  • Enables direct connection of SIP-enabled devices without the need for gateways

Cloud Communications

Cloud communications includes all your voice and digital communications that can be routed over the Internet with protocols such as voice over IP (VoIP). Cloud communications have intrinsic advantages over traditional switched communications on the public switched telephone network (PSTN). The advantages arise from the robust selection of communications protocols available on the Internet, including VoIP and SIP.

VoIP telecommunications services excel in features and scalability, and today, VoIP is extending past PSTN in call quality, security, and affordability. VoIP solutions that power cloud communications can also integrate with existing PBX equipment to provide powerful hybrid solutions. Recent hybrid VoIP studies show that 39% of cloud solutions users rely on a hybrid solution, and that this number is expected to increase to 61%. Moreover, hosted PBX implementations are growing in popularity.

Some of the benefits and virtues of cloud communications configurations and hosted PBX solutions based on VoIP include these.

  • Encryption available via Transport Layer Security (TLS) provides en-route security
  • Secure encrypted virtual private networks can be configured
  • Quick to deploy
  • No on site equipment required for cloud hosted PBX systems
  • Near instant scalability
  • No investment cost for on site equipment
  • 24×7 coverage provided with flat monthly hosting costs
  • Rich features including call forwarding and call recording

SIP Trunking and Cloud Communications Work Together

A SIP trunk can be used to carry your voice calls, converted to digital internet packets, to your VoIP service provider. From there, your voice traffic can be transmitted over the Internet to the called party, or directed to the public switched telephone network (PSTN)for delivery to your called party.

You can optionally use a gateway to let you continue to use your existing legacy PBX. On an outbound call, your voice signal is transmitted from your PBX to the gateway at your site. There the call is changed from a voice signal to a data packet and sent across the internet to the AVOXI Operation Center gateways. The gateways change the data packet back into a voice signal and push the call over the PSTN to its destination.
