Virtual and Self Cloud PBX based VoIP

PBX systems allow you to configure extensions, customer management systems, auto attendant, call
redirects and more to route calls within your organization. These operations are handled through a
server private branch exchange (PBX). Virtual PBX Services setup, maintain and host your exchange
server off-site and simply buy IP phones and an Internet connection to interact with a panel of web-
based management. Self -Hosted PBX brings the exchange server in-house (on site). The benefits and
compensation vary, but in general, virtual PBX services are for small businesses, and Hosted PBX systems
are for medium and large companies with heavy phone volume. You can use either analog or digital
phone lines with VoIP PBX Auto -Host. Services are limited to virtual PBX VoIP. focuses
exclusively on cost savings (typically 50 %) associated with business grade VoIP communications.


The general consensus is that the virtual PBX services are ideal for small businesses with 1-10 employees
only. With Virtual PBX, you are sharing the third party server exchange with others; therefore, share the
cost of hardware and maintenance. You should pin point your needs and carefully research your favorite
virtual PBX provider. The costs are usually between $ 30-120/month complete packages (including
minutes). Extensions may or may not be free, depending on the provider. The marginal cost will increase
compared to self-hosted PBX system as you add more users.

Virtual PBX systems will also provide you with DID and SIP trunks instead of the security of your account.
However, they may limit the number or channels or simultaneous calls your phone number can be
achieved (services vary).

For PBX Hosted systems need a server (with port PCI data), the configuration software (open source
available), broadband (t1 handles 30 simultaneous calls), and potentially a firewall or gateway. Plans
VoIP rates are provided through ITSP (Internet Telephony Service Providers) and charge you at least $
15/SIP Trunk per month and $ 1/DID per month (rate plans and packages vary by provider). As a general
rule, you should reserve channels (DID, etc.) to one third of its employees. If you have 300 employees,
not all of them will be on the phone at all times. Calculate a secure means of simultaneous calls
required. Each service provider is responsible for terminology (SIPs, DID, canals, etc.) differently. Contact
your support department with requirements / specific questions such as:

"We need 20 simultaneous incoming calls to our toll free number and 2 simultaneous calls to our local
"We need about 5000 incoming minutes on our toll free number 1000 outbound minutes to Australia ,
and 1200 outgoing minutes our satellite office in Germany? "

"If our phone systems go down, we can redirect incoming traffic to another phone ? "

"We have 4 different numbers, with ' x' number of staff handling simultaneous calls ' x' in each

"How do you drive, and what is charged to the numbers of input and output ports of your system? "

Bottom line: if you need more than 25 simultaneous calls (more than 75 employees ) , consider a hosted
PBX system itself. If you are unfamiliar with PBX systems , spend at least 1 month to investigate your
options before equipment and services ( ensuring compatibility and features) to buy . You need a
compatible phone, server / software, firewall, internet data / voice and SIP / DID providers .


Many tout the hosted PBX hardware itself can cost as much as $ 60,000. However, you need to research
your company, as many hardware vendors can sell a complete PBX configuration ( compatible phones
and server / installed software) for small businesses in the area of $ 2500.

Depending on your needs and volume, enterprise level pipe can be as high as $ 600 a month. For the
most part , simultaneous calls is limited to your bandwidth (eg 23 simultaneous channels/T1 ) . In
addition, some SIP providers require a static IP address. With Virtual PBX , businesses can use a standard
Internet connection data that may not be practical for large support centers / sales. However, both IP -
PBX systems allow you to share the same bandwidth for data and voice. Be sure to set the QoS ( Quality
of Service) settings to prioritize voice calls and to avoid poor sound quality fell.

For both systems you can use the SIP IP phones or soft phones enabled . You can also use a traditional
phone, but an ATA gateway for VoIP service (check interoperability close ) or adapter is needed. The
self-organizing      systems          may         require       a         SIP        firewall        .

With Virtual PBX , which uses a server and service that is beyond their control and that is compromising
the safety and reliability risk .

With hosted PBX itself, you select your ITSP (Internet Telephony Service Provider) for SIP trunks. You are
not limited to a single supplier. You can set up rules within Asterisk , for example, to send some calls to
an ITSP , and other calls to another ( maximize the benefits of individual providers ) . In addition , you
can have ITSPs backup if a SIP is dropped ( you can set up automatic error control rules for this too ) .
Virtual PBX providers do not allow such a configuration, although presumably their back-end processes
have these internal backup mechanisms in place.

Many , not all, virtual PBX systems limit simultaneous calls per number. What is your technical ability ?
Do you have the time and ability to maintain a hosted PBX system in itself? If you do, even with fewer
users a hosted PBX system itself could be a cost saving. However, if you have time , use virtual PBX ,
meanwhile , according to an analysis of profit / strict savings.
