What is VoIP?

Voice-over-Internet Protocol (VoIP) is a protocol that enables
transmission of speech over the internet or other IP packet-switched

VoIP converts the voice signal from a telephone into a digital
signal that travels over the IP Network, then converts it back at the
other end. Now widely accepted, VoIP technology is being rapidly
deployed and is now a core part of all new telephone systems.

The technology is continually being extended to integrate with the new Web 2.0 Internet that exists today.

Competitive Features

VoIP is undoubtedly the future of telephony, now offering
capability, flexibility, quality and resilience that are a far cry from
the limitations of earlier systems.

Many features and advantages make it the ideal business solution:

  • VoIP provides a lower cost alternative to the traditional networks
  • Call costs for businesses systems are substantially lower than ISDN
  • VoIP is scalable on an individual channel basis and extra phones can be added without additional telephone cabling.
  • For multi-site organisations all internal phones can be on the
    same network, so calls between sites within the organisation are
    potentially toll free.
  • Number portability is assured and simple, even when moving long distance.
  • Disaster recovery is fast, with same day line switching to an alternate location
  • Conference calling, call forwarding  and caller ID are all low-cost features.
  • Integration with other services such as voicemail, email and SMS is straightforward.
  • Advanced features such as videoconferencing are easier and cheaper to implement.
  • Advanced DDI offers comprehensive management and analysis tools
  • Emergency services are supported
  • VoIP is ideally suited all businesses, and higher volume
    customers financially benefit even further, as the capacity requirements
    increase without linear increase in connectivity charges

The Bottom Line

VoIP technology has now matured to offer comparable if not more
dependability than traditional ISDN-type services. This, combined with
low lifetime cost and fast ROI, is presenting decision makers with an
overwhelmingly compelling business case.

SIP Trunking

VoIP calls are made up of two components – the call signalling and the call media. In other words, in order for one phone  to  connect to another phone, we need a way to set this up using telephone numbers - and then make voice crisscross between the handsets.

There are a couple of standards for VoIP,  initiallyH323 and now SIP.  A SIP Trunk is a logical connection between two endpoints, such as a phone system (PBX) and a Service provider such as Buzz Telecom. (The word “Trunk” is used in telecoms to mean more than one – so a SIP Trunk can typically carry more that one phone call, however it is possible to connect a single SIP telephone directly to Buzz Telecom without using a PBX

Buzz Telecom  provide only business grade telephony. All our calls are originated and terminated directly with our tier 1 partners using private resilient circuits.

Here are some of the Key Benefits of Buzz Telecom’s SIP Service

  • Cheaper than an ISDN service. Savings can be used within Return On Investment  calculations
  • Being able to have to have multi-regional numbers from one location
  • Advanced enterprise network features and call routing
  • Number portability is assured and simple, even when moving long distance.

SIP Trunking Add-ons

Single user “SIP Accounts” are provided to customers with SIP Trunks into their PBX. This feature provides Teleworkers with an extra phone number they can use when out-of-the-office. IP Telephones (including mobile softphones) connect directly to Buzz Telecom and can benefit from our fully secured SIP technology.
