Voice over Internet Protocol (VOIP)

VoIP covers many different things but essentially it is a service offered by an Internet Telephony Service Providers (ITSP) like inCloudOne® who connects your company's Private Branch eXchange (PBX) telephone system to the Public Switched Telephone Network (PSTN) via the Internet or an alternative connection.
This connection is achieved using a SIP Trunk/Channel(s) and can be seen as a viable alternative to traditional ISDN

SIP Trunk

Trunk can be thought of as a large pipe that all voice calls are carried over.

• Once setup inCloudOne will give you one of these for FREE each month

SIP Channel

Channels are responsible for carrying the individual voice call. You will need as many channels as you intend to make concurrently calls, in effect SIP Channels are sold like ISDN30e lines, so if you require 10 concurrent calls at the same time then you would order 10 SIP Channels and rent these on a monthly basis.

However, if you have 10 phone users working in the office it is unlikely that you will need 10 SIP Channels. It is unlikely that everyone will be on the phone at the same time, so you can save money by selecting less SIP Channels than phones/people.

If you find you need more SIP Channel as your business grows, then we can simply upgrade you. If you not using what you have then we can also downgrade you. This method is very flexible as it can be adjusted to suit your changing business needs and seasonal trading.

inCloudOne does not lock you into longterm contracts and so if your requirements change we will change the solution to suite you.

• SIP Channels can be added and removed as required and are sold in easy to deploy blocks of 2, 4 & 8.

Connection to your office

Internet based SIP Channels are not guaranteed as the voice is carried across the internet where latency and jitter can not be controlled.  iC1Connectivity dedicated lease lines and voice assured circuits should be used with SIP Channels in order to guarantee the number of concurrent calls.

Q: What is SIP?

A: SIP stands for Session Initiation Protocol. It is designed to set up connections between devices such as computers, phones, PBXs, video conferencing units and servers.
The actual voice is carried using another protocol called Real Time Protocol (RTP) and is sent as normal IP packets.
The IP traffic can be connected over a public internet connection using your existing broadband connection. Unfortunately broadband providers do not like this as they make no revenue from these connections and most residential grade broadband services have not been designed to carry voice grade services.

Q: What is SIP Channel?

A: A SIP Channel is a virtual phone line that connects your PBX to the public telephone network. It sends the data over a data network, instead of over an ISDN circuit. SIP Channels can be used instead of ISDN circuits to carry all of your telephone calls, or in conjunction with an ISDN circuit to provide a resilient telephony solution.

Q: What are the advantages of using SIP Channeling rather than ISDN?

A: SIP Channels utilise your existing data connection, thereby negating the need to spend money on monthly line rental for ISDN circuits.
Calls sent over the Internet are much cheaper than calls sent over traditional telephone infrastructure, thereby saving on your monthly call costs.
Because SIP Channels are provisioned over your existing data connection, provisioning can be done instantly as you do not need to wait for circuits to be installed.
Unlike with ISDNs where you have a maximum of 30 channels per circuit, a SIP Channel is fully scalable so you can have as many or as few as users as you want.

By retaining on of your old ISDN circuits, you can add resilience to your phone system, thereby ensuring that even if one of your connections goes down, your telephones will continue to work at all times.

Q: When should a business use SIP Channeling?

A: SIP Channeling is relevant to your business if you use ISDN2 or ISDN30 circuits, and if you get your Internet connectivity through a leased-line or a dedicated SDSL.

SIP Channeling is irrelevant to your business your business is too small to use ISDN circuits, and if you use contended ADSL or Wi-Fi to provide your Internet access.

Q: What equipment do I need to set up SIP Channeling?

A: If your PBX is older than a year or two, you probably need a little box called an SIP-ISDN Gateway. It acts as a translator between the SIP of your SIP Channels, and the ISDN interface of your PBX.

If you have an IP-PBX made in 2008 or later, it probably supports SIP, without any need for a gateway.

Q: Will I need additional connectivity to use SIP Channeling?

A: Yes. Although it is possible to run SIP Channels over the public Internet, we wouldn't advise it. Phone calls are sensitive to delay, variations in delay and data loss (aka latency, jitter and packet loss). For this reason, we never sell SIP Channels without connectivity.

Q: How many SIP Channels will I need?

A: That depends on how many simultaneous calls you expect to take place at one time. Obviously, this will depend on your business. If you're running a call centre it could be one SIP  per operator. For more typical companies, you'd usually have one SIP Channel for every 5 or 6 phones.

Q: Are SIP Channels reliable enough?

A: Set up correctly, SIP Channels are more reliable than ISDN. Set up incorrectly, and they're less reliable. The key thing isn't the 'SIP' bit, but the 'data connectivity' bit over which the SIP Channel runs. To get good reliability you need a direct connection to your SIP Channel provider. You also need there to be a backup connection of some sort.

Q: Are SIP Channels expensive to implement?

A: Chances are it will save you money.

Up front, you'll need to pay for a direct connection to your SIP Channel provider (to ensure good call quality). You'll probably also need a SIP-ISDN gateway.

As soon as the service is live you'll save money on your connectivity (because the data connection will be cheaper than your existing ISDN circuit rental). You'll also save money on your line rental and on your calls.

So the switch from ISDN30's to SIP usually pays for itself.

Q: What services will SIP support?

A: Most of the functionality you associate with your phones is really provided by your PBX. So whether your using SIP Channeling or ISDN Channeling makes no difference.
