Why businesses choose SIP Trunk Services
A SIP trunk connects your office phone system (IP PBX) or contact centre to the public phone network using your data connection instead of copper or PRI lines.
You choose how many calls can run at the same time and can increase it without new cabling. It's usually the first step when replacing PRI lines.
What's included
- Flexible channelsIncrease or reduce simultaneous calls as needs change.
- Number blocksDID numbers for direct dialling to people and departments.
- Works with common PBXsCompatible with most IP PBX and contact centre platforms.
- Quality over a managed linkRun it on a leased line or MPLS for clear, stable calls.
Best suited to

What changes for your business
You stop paying for idle PRI capacity and can add call channels the same day you need them. Calls between your offices can also travel over your own network, and adding numbers for a new team no longer needs a site visit.

Questions about SIP Trunk Services
Do we need a leased line for SIP trunks?
A dedicated or managed connection gives the most reliable call quality, especially for many simultaneous calls.
Can we keep our PRI numbers?
In many cases numbers can be moved to SIP. We check this before migration.
How many channels do we need?
Check how many calls run at the same time during your busiest hour. We size trunks with some headroom above that.
Does SIP support fax?
Fax over SIP is possible with the right equipment and settings, but many businesses move to email-based alternatives.
Is SIP Trunk Services available outside Delhi NCR?
Yes. We're based in New Delhi and serve businesses across India, including Mumbai, Bengaluru, Hyderabad, Chennai, Pune, Kolkata and Lucknow, through our carrier and technology partners. Availability is confirmed for each location before you sign.
