SIP and mSIP: What a Difference an “M” Makes, and Why You Should Know What It Stands For
July 26, 2017
The unpredictability of the Internet and lack of visibility into service performance used to be a concern for users of SIP Trunking, until nexVortex delivered mSIP (Managed SIP)
VoIP for business just keeps getting bigger and better. Bigger, meaning that the adoption rate has taken it from early adopters to mainstream. Better, meaning that quality of service (QoS) plus definitive troubleshooting, (two roadblocks to adopting SIP for some businesses), have been removed by nexVortex’s mSIP Trunking Service.
What made this possible? Session Initiation Protocol (SIP) is what made VoIP possible. It is the protocol which connects a premise-based PBX to the network to make phone calls more cost effective, more flexible, and more redundant than using older methods like PRI or analog lines.
SIP chops through many cost barriers. Because SIP runs over an IP network (like the Internet), you no longer have to maintain one network technology for your voice and a separate one for your data. With SIP, voice can run over the same network which handles your Internet traffic.
The big “but”
But with that ability also comes some issues. When a voice call leaves the premise and is carried over the public Internet on its way to its ultimate destination (aka the “called party”), it can be subjected to latency, jitter and packet loss which negatively impact voice quality, (see our earlier blog on this topic). In addition, because the Internet is a “network of networks” there is no good method to provide definitive troubleshooting if an issue arises. This is because there can be multiple carriers involved in the handling of the call packets along their path. This is not to imply that SIP Trunking over the public Internet is a bad service — it meets the needs of many businesses. But many medium and large businesses or those with mission critical voice applications wanted assurance of a better quality service and for them “good enough” was not good enough. As an innovator and one of the first to deliver SIP Trunking (for over 11 years), nexVortex set out to raise the bar and deliver voice quality with definitive troubleshooting while addressing QoS for SIP Trunking and that solution is called Managed SIP (mSIP).
The “M” in mSIP makes all the difference
Standard SIP Trunking can work for many companies. Its performance may meet your needs but companies which have historically used PRI for PBX interconnection were looking for a “PRI equivalent service” using SIP Trunking which could provide both voice quality and definitive troubleshooting.
So, bring in that “m”. It stands for “managed”. Managed SIP (mSIP) Trunking is a service offered by nexVortex which not only delivers voice quality but which comes with the ability to definitively troubleshoot issues at multiple points along the call path – from the premise, over the access network, and across the core to the Public Switched Telephone Network (PSTN).
It began with a large investment in infrastructure by nexVortex including building out a nationwide private MPLS network to carry VoIP calls, not over the public internet to the PSTN but over a private (controlled and quality assured) IP network (monitored and managed by nexVortex).
It continued with nexVortex choosing ADTRAN equipment to reside on the customer premise to provide a demarcation point between the customer premise and the access network where voice quality could be measured and reported on BEFORE voice left the customer’s location.
From there, nexVortex executed peering agreements with most major carriers to ensure that calls stayed “on-net” between the access carrier’s network and the nexVortex private MPLS core (less hops, means better quality). Finally nexVortex initiated a massive software development effort to deliver the tools to collect, analyze and report on voice quality at multiple points along the call path (from the premise, over the access, through the core, to the PSTN). Not only does the service deliver QoS for voice but the implementation and tools provide the ability to definitively detect, isolate, report on, and address issues all along the voice path. This and the extensive interoperability testing nexVortex does with leading PBX platforms such as Mitel and Avaya provide confidence to our partners and customers. mSIP was selected as a multiple category award winner for ChannelVision Magazine’s 2017 Visionary Spotlight Awards.
If you insist on quality and definitive troubleshooting, you’ll want to insist on the nexVortex mSIP Service. nexVortex answered the industry’s call to delivering a “PRI equivalent” service for SIP Trunking which now allows companies to enjoy the cost savings and scale of SIP Trunking while confidently replacing outdated and soon to be retired Primary Rate Interfaces. The “M” makes all the difference.
