Convert Traditional Phone Systems to SIP
If you already have an expensive traditional phone system in place, you might be hesitant to make the switch to SIP. After all, replacing an entire phone system can be a major undertaking, both in terms of time and money. But the good news is, you don’t have to replace your entire system to enjoy the benefits of SIP.
Rather than change your phone system, we can help you maintain your existing setup and convert your phone calls from analogue to SIP Trunks. With analogue calls being phased out within the next 2-3 years, it’s important to start planning your roadmap now.
So, if you’re looking to upgrade your existing phone system but don’t want to replace the whole thing, converting to SIP might be the perfect solution for your business. With in2tel’s expert guidance and support, you can make the transition to SIP with minimal disruption to your business.
