Questions
Thinking about making the switch to UCOM SIP Trunks, or just want to know more? We've answered the most common questions right here. Can't find what you're looking for? Our Team is always happy to help.
A SIP Trunk is a virtual phone line that uses your internet connection to deliver voice calls, replacing traditional phone lines and allowing for more scalable, cost-effective business communication.
A SIP Trunk channel is essentially one line of communication, it supports a single active call at any given time. If three members of your team are on calls simultaneously, that uses three channels.
The number of SIP Trunk channels you need comes down to how many calls your business handles at the same time. Each channel supports one concurrent call, so if your business regularly handles up to five simultaneous calls, five channels is your minimum. As a general rule of thumb, a ratio of one channel for every two team members is a good starting point, though your ideal number may vary depending on the nature of your business.
Our SIP Trunks use advanced encryption and industry-standard security protocols to ensure every voice call remains private and protected from end to end. All communication traffic is encrypted, safeguarding your business against unauthorised interception or eavesdropping.
Absolutely. UCOM supports number porting so you can retain your current business numbers without any disruption. Our porting process is designed to be downtime-free, keeping your business connected throughout the transition.
