SIP Trunking stands as Session Initial Protocol and it is the process of conveying the voice and other unified communication services on the internet platform. People communicate in this world through video, chat, and voice, but they don’t realize SIP Trunking is the platform for all three, and they can use it so well.
The SIP protocol enables VoIP sip trunk. Traditional telephones were used initially but now SIP Trunking takes the place over it and it works along the IP-Pbx. A SIP trunk is a virtual phone line that lets users place and receive calls over the internet to anyone with a phone number who has a SIP address.
With SIP trunks, voice calls are converted into digital packets and sent across a network to their final destination. SIP channels are supported by every SIP trunk. There are 24 SIP channels per trunk. There is no limit to the number of channels a SIP trunk can hold, so your business only needs one SIP trunk no matter how many simultaneous calls it expects. Your business will need a certain number of channels based on how many calls it makes at any given time. SIP Trunking involves the
- Scalability
- Extensive Cost Savings
- Convergence
- Business Continuity
- 24/7 availability
Difference between Scalability and High Availability
One of the attractive cost benefits of SIP trunking is the technical ability to centralize PSTN access for the enterprise into a single large pipe. Doing so creates several design considerations, including both scalability and high availability:
Scalability
Routing all calls from the entire enterprise over a single number of centralized SIP trunk access points means that you need a SIP trunk capacity of several hundred to several thousand connections.
This implies border handling session capacity equipment that often far outstrips any single TDM gateway that exists in the typical enterprise. Most enterprise gateways are in the 1 to 16 T1/E1 range that equating up to between 384 to 480 sessions. Even a T3 gateway, a relative rarity in the average enterprise, presents only 672 sessions.
Some of the redundancy schemes covered in the remainder of this section simultaneously address scalability mechanisms including higher-capacity equipment and load balancing over clusters of individual boxes.
High Availability
The more sessions that are entered into a single physical pipe, the larger the business impact to your organization of this single point of failure. For this reason, few enterprises truly deploy a single SIP trunk entry point into their networks; there are almost always multiple points.
How SIP Trunking helps in Business Growth
SIP Trunking is proved to be beneficial for the growth of business and it reduces the cost of communicating. There are a few terms by which you can easily understand that SIP Trunking is best for the business:
- They are cost-effective
- Customizable
- Flexible and reliable
- Trunk Redundancy
Your business will no longer have to add one phone number per line as it grows, and you will have more flexible pricing options that make SIP trunking more scalable and more affordable than ordinary telephone systems.
Reduce cost
- Offered International calls at a very reasonable rate.
- If you have offices located in multiple countries, you will benefit from free calls between them on the same VoIP system.
- SIP providers allow you to add lines and numbers only when you need them.
- A unified communications (UC) platform can be used to implement it over the cloud via WAN.
Flexibility
- PRI Phone Access is sold in units of 23 channels, so subscriptions can occur on far more channels than your business needs.
- Enables hybrid phone systems such as SIP trunking that are built-in with traditional phone services.
Reliability
- SIP trunking is based on broadband connections rather than managed PSTN infrastructure, allowing SIP trunking providers to access and control geographic regions that do not own the infrastructure.
- SIP trunking provides failover to mobile phones in case of data loss.
- Ideal for businesses with multiple locations and remote workers.
- SIP trunking and VoIP improved data redundancy.
Trunk Redundancy
There are always multiple SIP trunk entry points into an enterprise network for redundancy purposes. This ensures that calls have alternative routing points if an equipment or building power failure occurs or a natural disaster in a particular region occurs.
The only realistic alternative to multiple SIP trunk entry points is to have a single SIP trunk and maintain TDM gateway access to the PSTN for failover, a scenario discussed later in this section. For small, single-site businesses, cellular phone access might be a realistic alternative to a single SIP trunk, but this is rarely practical for a multisite enterprise of any size.
Consider three different areas of SIP trunk redundancy:
-
Local redundancy:
Most SIP trunk services offer at least two IP addresses. Local redundancy protects against equipment failure or power failure to a single piece of equipment. These two IP addresses should ideally terminate onto two redundant border elements. Most providers offer either a primary/secondary or a load-balancing scheme that the enterprise can choose from.
-
Geographic redundancy:
Most medium-to-large enterprises prefer to bring in the two IP addresses or perhaps two different SIP trunks (that is, four IP addresses, each SIP trunk with local redundancy) into two separate buildings, likely data centers, in two different geographies. This protects against natural disasters and buildingwide power or other outages.
-
Service provider redundancy:
Some enterprises and contact centers get SIP trunks from two different providers, both for least-cost routing opportunities and for redundancy purposes. If one provider is having problems, the other provider’s facilities can carry all traffic. This scheme is easy to implement for outbound traffic but harder (due to DID mapping) for inbound traffic.
Conclusion
SIP Trunking is the best way for communication all around the world with the easy way. Here you have the ability to create multiple extensions at a single number on your premises. WavetelBusiness provides you with affordable rates a platform on which you can call, chat, and video all over. SIP Trunk is beneficial for business growth and it plays a major role in cost saving.
