SIP Trunks
Keep the phone system you know, but replace its old lines with digital SIP connectivity, often at a lower monthly cost.
What are SIP trunks?
SIP trunks carry your calls over the internet instead of over old ISDN phone lines, while you keep your existing on-site phone system. They are the modern replacement for ISDN lines, and they usually cost less while adding flexibility.
If your phone system itself is also due for replacement, a fully hosted VoIP system may make more sense. We'll look at your current setup and tell you which path is right.
Why businesses switch to SIP
- ISDN is being retired, so you need to move anyway
- Lower line rental and call costs for most businesses
- Add or remove channels quickly as call volumes change
- Keep your numbers, and add numbers from any area code
- Built-in options to reroute calls if a site or line fails
Frequently asked questions
Q: Will SIP work with our current phone system?
Most modern on-site systems support SIP. We'll check yours and confirm before recommending it.
Is it reliable?
Yes, on a suitable connection, and we can add resilience so calls reroute automatically if a line fails.
Do we have to replace our handsets?
No. With SIP you keep your existing system and phones, you are just changing the lines behind them.
When should we switch?
Sooner rather than later, so you start saving and avoid a rushed move.
