Benefits of Grandstream IP Telephony

Cost savings, mobility, and scalability are some of the key advantages of switching to IP Telephony.

1. Cost

With IP Telephony, the cost to your business is generally consistent and predictable as the charges that occur come from the internet service provider.

2. Mobility

With a rise in remote working, co-working, and hybrid setups, the use of IP Telephony significantly improves your ability to be agile. This allows your teams to set up their phone service from anywhere.

3. Unified Communications

IP telephones are popular for connectivity reliability and for transporting voice data over the internet. The popularity of IP telephony systems has also enabled the development of UC (Unified Communications). This allows businesses to benefit from communications functionality, including voice calls and video conferencing all on one platform. 

4. Scalability

Using Grandstream IP Telephony over analog telephony means you don’t have to pay separately to add extra phone lines. IP Telephony Services have fewer restrictions, allowing you to scale up or down.

Features of Grandstream IP Telephony

IP Telephony empowers businesses with a much broader range of functionality and capabilities to make their business much more efficient in a modern working landscape. Below are the advantageous features of an IP phone system (IP PBX).

HD voice: Essentially ‘High Definition’ voice means users can leverage a more seamless, clearer quality of sound that wipes out background noise.

One number: Investing in IP technology allows users to have one single phone number to call from different handsets.

Least call routing: Least call routing (LCR) allows you to economize by letting the system automatically establish the best way to route your calls. This ensures that the pre-set, lowest-cost option will be usually selected as the routing path for each external call.

Call handoff: Call handoff is a feature that means users can switch from one device to another seamlessly and without audible disruption. For example, users coming to the end of their day can switch from a desktop to a mobile device. They continue their call as they shut down.

Fixed-mobile convergence: For many roles, such as sales and client servicing or support, businesses need an ‘always on’ model for these profiles. Fixed Mobile Convergence means that a mobile phone can act as another hub with all the functionality of the phone system. This includes call transfer and conference features.

Grandstream IP Telephony Protocols

Session Initiation Protocol

Session Initiation Protocol (SIP) is a signaling protocol that establishes a ‘session’ between two or more participants.


Similar to the SIP protocol, H.323 boasts the same functionality. The H.323 protocol is commonly used for the initiation, modification, and termination of a session.

Real-time Transport Protocol (RTP)

This protocol features a packet format for the transmission of audio or video in packet format across the internet. We mostly employed this for streaming television services, video conferences, and voice media.

Real-Time Transport Control Protocol (RTCP)

This protocol works in tandem with RTP defined in RFC 3550. It is the protocol accountable for transmitting control packets, the respective recipients of a call.

Secure Real-time Transport Protocol (SRTP)

Secure Real-time Transport Protocol, defined as RFC 3711, is always used for WebRTC technology as one of the security protocols. It adds security elements, like message authentication and confidentiality.

Session Description Protocol (SDP)

Published as RFC 4566, SDP is the internet protocol standard for defining the type of multimedia communication session for session announcements and invitations. This protocol supports streaming video conferences and voice-over IP applications.

Factors to consider when installing the Grandstream IP telephony system

What connectivity do you currently have in place and is it suitable to run voice?

One of the most important elements of a VoIP solution is the IP internet circuit. To ensure business-grade call quality, the internet circuit requires a certain level of guaranteed performance. Normal DSL broadband circuits do not provide guaranteed performance. Only DSL circuits that have performance SLAs designed specifically for voice are suitable. Ethernet circuits provide suitable performance SLAs and, if correctly configured for QoS (Quality of Service) they can prioritize voice traffic ahead of normal data. This makes them suitable for use with both voice and data simultaneously.

At Hubtech limited, we will always consider the IP connection when providing a voice solution. We strongly recommend running voice over Fibre Ethernet, Fibre Broadband, or an SDSL M connection with guarantees on the quality of voice.

What features do you require for your phone system and will your requirements change in the future?

VOIP offers a far more versatile way of working compared to traditional telephone solutions. It allows you to create a more functional, efficient, and ultimately more profitable working culture. It will also give you more flexibility with telephone numbers. This flexibility is also valuable when designing your disaster recovery plans.

At Hubtech limited, we will always do our utmost to gain a full understanding of your business. These include what you do, how you operate, and the number of sites to allow us to better tailor a VoIP solution to your business.

How long does it take to install a new phone system and when do you want the new system in by?

There are many unique elements to installing a phone system. There is the hardware to prepare, the configuration of the phone system, the integration with the LAN network, and the numbers to port. If your business cannot run without the ability to make calls then this needs to be a chief priority when moving. Also, if you are upgrading an existing phone system, then consider why you are upgrading. Is it reduced cost, improved productivity, flexible working, or maybe all three? The quicker the system is in place, the quicker you will start benefiting in these areas.

At Hubtech limited we ensure your business gets the phone system it needs. But you also need the system to be ready in time.

How will you implement a new phone system with minimal disruption to your business?

Making a change to your phone system can disrupt a business. Not only by changing our handsets and installing new hardware but also through a change in business culture. New features you want employees to use, working from a softphone rather than a desk phone, working from mobiles, etc. It is important to consider when you plan to implement a new system and if you have suitable training planned for the system. If you are a cyclical business, replace your phone system in the off-season or for other businesses to install it in their quieter months. You should also have a plan in place to ensure you continue to receive calls for an install period.

At Hubtech limited, we will always discuss and implement a plan during the upgrade of a phone system. It includes call diversions for business continuity and adequate training for the staff on the new phone system. A well-planned install process can considerably reduce the disruption caused to a business when upgrading your phone system.

What is your disaster recovery plan?

It is very easy to get carried away by focusing on the new features and functionality of the system and neglecting the disaster recovery plan. Ask yourself what will you do if your phone lines go down or you have a power cut. Also what if the system goes down? Finally what impact will this have on your business?

All Hubtech limited’s VoIP Phone solutions have built-in disaster recovery options. Moreover, we discuss this to ensure we design the disaster recovery plan around the business and not just a standard backup plan. Whether this is diverting calls to a single mobile, or multiple mobiles, we will agree on a plan that fits your business.
