12 Protocols for Secure VoIP Communications

Rather than dealing with a telecommunications box packed into a crammed closet, those who choose VoIP will enjoy cloud-based services that streamline the communication and collaboration of your team. From virtual meetings to around-the-clock contact center solutions, you'll have peace of mind knowing that your connections are clear, responsive, and supported by the right protocols.

Protocols are used by VoIP services to transmit data from one IP address to another. Anything you share between endpoints, whether it's an image, audio file, or video clip, the data is sent through a certain protocol that your provider maintains. With that in mind, the type of provider you have will ultimately determine the kind of protocols you have at your disposal. However, there are a variety of channels to be aware of when it comes to certain exchanges.

To give you an idea of what kinds of protocols are used on a regular basis among providers, here is a rundown of what they are and how they're used to ensure the best communications:

12 Protocols that Transmit VoIP Information

An important factor to understand before diving into the background of each protocol is that VoIP services use channels that are either proprietary or open standard. Essentially, a proprietary protocol is one that's owned by a single organization or entity, whereas an open standard protocol is available for public use under the guidelines of various rights and properties.

Needless to say, the type of protocol used is dependent upon the type of information transmitted and the way it's processed.

1. Session Initiation Protocols (SIP)

As mentioned earlier, your provider plays a significant role in the type of protocol used to send information. For example, traditional PBX providers rely on SIP, a signaling protocol used to initiate real-time sessions of voice, video, and messaging applications, to ensure secure open standard connections.

2. H.323

H.323 is another protocol used by traditional providers because it was one of the first protocols used for VoIP technology. What makes this protocol unique is that it uses a series of protocols, such as ISDN, PSTN, and IP to transmit data. Although, newer developments have limited the benefits of H.323, making it best suited for processing extended network traffic.

3. Media Gateway Control Protocol (MGCP)

Media gateways are used to process information and route them to the right user. A MGCP aids this step by establishing a secure management connection.

4. H.248

In relation to MGCPs, H.248s establish connections for media gateways over traditional public networks, like public switched-telephone networks (PSTN).

5. Real-time Transport Protocol (RTP)

In order to stream media between entertainment systems, RTPs are used as a transport protocol for audio and video files in real-time.

6. Real-time Transport Control Protocol (RTCP)

RTCP is an additional protocol used for RTP connections that offer data on stream statistics and status updates.

7. Secure Real-time Transport Protocol (SRTP)

Encryption is always the safest way to send sensitive information, and SRTPs are basically an encrypted version of RTP gateways.

8. Session Description Protocol (SDP)

Whenever a transmission is made, the information can be identified as a specific file format, and SDPs are used by SIPs to distinguish VoIP connections.

9. Inter-Asterisk eXchange (IAX)

An IAX is a specific type of protocol used between VoIP servers. This means that cloud-based providers who primarily use VoIP will establish this type of connection between endpoints in-house or with other external VoIP servers.

10. Extensible Messaging and Presence Protocol (XMPP)

When using instant messaging or updating contact lists, XMPPs are used to manage transmissions and file them accordingly.

11. Jingle

Jingle represents a peer-to-peer exchange session that commands the transmission of XMPPs. Basically, whenever you you instantly connect with a team member via instant messaging, then a Jingle is established. Also, this serves a semi-proprietary protocol created by Google that can be used on open standards.

12. Skype Protocol

Lastly, a Skype protocol is a proprietary communications service that establishes a peer-to-peer connection among users in a particular suite.

Now that you know the different kinds of protocols used with VoIP, you can better assess the needs of your team's communications and choose a provider that can offer you the best security.

Cloud-based VoIP providers offer the latest technology in business phone services. Users can take advantage of extension dialing, auto attendance, ring groups, and voicemail options, while exploring tons of new features that traditional landlines can't replicate. With VoIP technology, your team will have a wide range of business integrations tools, mobile applications, collaboration features, and online management suites that are second-to-none. Not to mention, switching to VoIP systems save companies an average of 50% on monthly phone charges, which is a great way to ring in the new year and generate progress moving forward.
