PRI to SIP Migration? Here are some considerations

PRI to SIP Migration? Here are some considerations

Migrating from PRI to SIP? You’re not alone. The demand for VoIP has increased in the last few years, thanks in part to improvements in technology and the rising costs of traditional ISDN access.
The landscape is getting bigger and only becoming more competitive, with Zion Research forecasting the market to grow from $85 billion in 2015 to $140 billion in 2021.
No longer then is it a question of “Why should I migrate?” but “When I do migrate, which provider should I choose?” With an expanding marketplace, it’s also no longer an option between your traditional telecom oligopolists - there are now hundreds of companies you can choose from that will have varying services and solutions.
Of course, there are plenty of factors to take into consideration when choosing the right provider for your SIP migration to satisfy your business needs.

SIP Flexibility

SIP was designed to be a flexible, more user-friendly alternative to TDM, so what good is it to migrate if you can’t find a carrier to deliver just that? Some providers understandably model their systems after traditional telecom providers of the past, and this is an unfortunate shortsightedness on their behalf. The technology behind SIP allows users a lot of freedom, so make sure that you choose a carrier that doesn’t limit your capabilities. Here are some of the features you should be looking for:
A self-service portal that gives you complete control over your telephony system The ability to instantly provision, segment and tag your SIP trunks A query that allows you to easily purchase and activate DIDs and toll-free numbers Real-time data reporting for immediate insight and analytics
Yes, these features do exist! And they’re available on our Mission Control Portal, so don’t get hornswoggled by other providers that restrict your potential when you do decide to move from PRI to SIP.


In addition to flexibility, SIP is designed to easily scale with your growing voice needs, so ask this question to the carriers you’re considering: “How scalable is your VoIP solution?”
When you’re expanding your business and suddenly in need of ten or a hundred phone numbers and connections, a next generation VoIP provider should be able to handle your request with ease. In fact, it shouldn’t even handle anything per se - the process should be something that YOU should have control over and not them - they should just be there to assist. And the entire thing should be automated - you find the numbers that you want and you activate connections instantly - anytime, anywhere.


Voice quality certainly is of utmost importance. This has always been the concern of a lot of companies switching from traditional phones to VoIP, and although the technology has dramatically improved in the last ten years, the internet was still not originally designed for VoIP. This puts the onus on the carrier to ensure that they are providing high fidelity voice services when offering SIP trunking.
When choosing the right carrier with when migrating from PRI to SIP, look for a provider like Telnyx that offers their own clean private global network to carry your media for you instead of using the traffic-laden public internet the entire way. You should choose a provider that proactively monitors your call traffic and that it’s being routed properly to ensure low latency and jitter.
Beyond the quality of the call, you should also investigate the overall service quality of the carrier you’re looking to work with. Online reviews like G2 Crowd can help validate and provide insight in terms of the support that you could be receiving. For instance, will you be getting dedicated account managers or 24/7 support? These are important factors to consider.


Moving from TDM to SIP should mean more money in your pocket. But although SIP is more cost-effective, you still need to watch out for VoIP carriers that lock you into long-term contracts and charge you for features that you’re not using. Again, this is simply an outdated model that takes advantage of users like you. SIP was created to disrupt the establishment, and how you pay for your services should reflect this.
Look for next-gen carriers like Telnyx that offer a la carte pricing with wholesale rates, so you only pay for services that you’re using. No hidden charges, no bundled pricing, no contracts.
