Some folks can tell you PRI is best whereas other vehemently support SIP. Reality is that each have their pros and cons. What’s best for your business comes all the way down to what you would like and may afford.
What is ISDN PRI?
PRI or Primary Rate Interface is a phone technology that delivers twenty-three voice channels associated one data channel to firms over an ISDN (Integrated Services Digital Network). The technology has been around for quite forty years. It's a physical line connecting a business to the telecom supplier.
SIP is a network technology, it’s not telecommunication primarily based just like the PRI. An SIP trunk is a virtual line, you don’t even need any hardware. SIP is additionally newer which suggests it supports digital options that aren’t available with PRI. SIP trunks deliver voice and data services to firms over the web. If you have got an IP-PBX already, you'll use SIP for your phone communications.
Historically PRI has delivered exceptional audio quality. But this doesn’t mean SIP cannot match it. In fact, with the correct set of tools and processes, SIP also can deliver exceptional quality.
Concerning PRI — as long as nothing happens to the hardware, calls can reliably connect. However, there are risks to copper lines similarly. They will get damaged by weather like snow or rain. Copper lines additionally degrade over time.
SIP at the same time can be reliable, provided you have got quick web connections and a decent service supplier. SIP lines don’t suffer from weather. They cannot be broken deliberately or accidentally. You can even use mobile fail-over options to make calls once the internet connection is down.
PRI is quite secure, despite the fact that there are risks like interference. Calls may be intercepted however since calls don’t ever leave the non-public and closed phone network, it’s tough for unauthorized users to breach security.
Being a network technology, SIP is subject to the standard security risks. Hackers may listen in on conversations, record calls, or perhaps commit fraud. Yet again, SIP may be made secure with the acceptable tools. With hardened firewalls, SBCs, VPNs, and cryptography, SIP systems are tremendously secure similarly.
Cost & Maintenance
If one thing happens to your PRI line, you’ve to invite a technician to come over and repair it. There’s just about no physical maintenance with SIP trunks, reducing prices even more. Over the long run, SIP offers you additional savings as you add extras like electronic communication, video conferencing etc.
This is one among the areas where SIP is the clear winner. Does one bear in mind that a PRI line comes with twenty-three voice channels? Therefore, you'll have twenty-three simultaneous conversations among the corporate. What if you wish additional, say 27? Well, you've got to shop for another PRI line that provides you forty-six channels. You pay money for an additional line despite the fact that you simply want four extra channels.
PRI isn’t terribly flexible. It takes time to scale. Suppose you’re within the middle of your annual contract and fired a dozen staff. You don’t want a pair of PRI lines any longer. Too bad, you’re stuck paying for them till the end of the year!
SIP suppliers allow businesses to feature SIP trunks with a web request. If you employ hosted PBX, you just need to add new users in the web portal. If your business downsizes for a few reasons, you'll take away lines similarly. You don’t have to be compelled to watch for a contract to expire or maybe the end of the month!
Which one is better: PRI or SIP for your business — boils all the way down to what you have got and wish. If you have got in house specialists and don’t have access to high-speed web, then PRI is appropriate. Except for most corporations, SIP can end up more suitable because it's the best choice for scale, flexibility, features, and not to forget — the cost!
