Introduction to cloud PBX

One of the latest spin offs of business telecom technology is the Hosted PBX. This technology allows small and medium-sized businesses to have a sophisticated telephone system without the investment in telephone equipment. In fact, the entire telephone system is operated and maintained by your Voice-over-IP (VoIP) service provider. A Hosted PBX lets employees work from their home, a hotel or on their cell phone while still being connected to the same office telephone system. Just like a Fortune 500 telephone system, you can transfer callers, put them on hold with music, set up conference calls or have the phone answered by an automated attendant who can direct callers to different departments. Key concepts behind a Hosted PBX service:

  • Your telephone system is “hosted” or operated by your provider
  • Works with your existing telephone service or completely replaces it
  • Can be used with landlines, mobile phones, VoIP service or might include VoIP service

1) What is SIP?

SIP means “Standard Initiation Protocol”. It is a set of protocol used for the communicate purpose. It transmits the Multimedia- media (voice, video etc.) over the internet as packets between two participants or group of participants. In VOIP, SIP uses RTP (Real Time Protocol) to transmit and receive voice data between phones.

2) What is SIP trunking?

SIP trunking is a Voice over Internet protocol (VOIP) which is based on Session Initiation Protocol uses data network to establish the connection between to two participants. This service would be given by ITSPs (Internet telephony service providers) equipped with SIP based private branch exchange (IP- PBX).

One of the reasons to convert to SIP trundling is because, cost of maintenance for SIP trunking is very low when compared to the traditional telephony systems. The primary diff. between traditional telephony systems is one have to maintain a separate and dedicated line for traditional analog telephone lines but in SIP trunking (VOIP) everything is “virtual”. So, no need of any maintenance. Another reason is when compare the VOIP with traditional phone system call cost is very low. One can save half of their phone bills with help of VOIP. On top of that, one can have DID numbers, Caller ID, IVR, Call forwarding etc. a lot of other exciting features.

4) How many SIP trunks do you need?

It depends on your business needs the concurrent calls will be decided. If the usage is normal, then one SIP trunk for 2 or 3 users is enough. Other significant thing is Internet connection. Since SIP trunk is an internet based service, it is good to have high bandwidth for exceptional call quality.

5) How much is it going to cost?

It depends on each and every provider. Some like to bill based on the outgoing calls. Some would ask the customer to pay some fixed amount every month and they offer unlimited services.
