Comparison
SIP Trunk vs PRI in Jamaica
PRI lines were the standard for connecting a business PBX to the phone network for decades. SIP trunking now does the same job over the internet — cheaper, faster to scale, and far more resilient. Here's the honest side-by-side for a Jamaican business.
| WOCOM SIP Trunk | Traditional PRI | |
|---|---|---|
| Connection type | Voice channels over the internet | Physical PRI circuit (23/30 channels) from the carrier |
| Upfront cost | Low — no new circuits or PRI cards | High — circuit install plus PRI hardware on your PBX |
| Cost per channel | Lower; pay for the capacity you use | Higher; buy a full PRI even if you need a few channels |
| Scalability | Add or remove channels in minutes | Locked to 23/30-channel blocks; adding means a new circuit |
| Setup time | Days | Weeks — physical circuit provisioning |
| Disaster recovery | Calls reroute automatically to other sites or mobiles | Tied to the physical line; down if the circuit or site fails |
| Multi-location | One trunk can serve many sites | Each site needs its own PRI |
| Works with existing PBX | Yes — keep your PBX | Yes, but needs PRI hardware/cards |
| Future-proofing | Modern, IP-based, actively developed | Legacy technology being phased out globally |
Which should your business choose?
For almost every Jamaican business today, SIP trunking is the better choice — it costs less upfront, scales channel-by-channel instead of in rigid blocks, sets up in days, and keeps working when a line or site goes down. It connects to the PBX you already own, so there's no rip-and-replace.
PRI still exists in older installations, but the technology is being phased out globally. If you're running PRI today, a WOCOM Flexi-SIP Trunk modernises your existing system without replacing it — and as an OUR-licensed carrier, WOCOM delivers the voice directly over its own network.
