SIP trunking questions

What is enterprise SIP trunking?
Enterprise SIP trunking replaces legacy PRI and ISDN lines with voice over IP trunks that connect your PBX or UCaaS platform to the public telephone network. We deliver elastic, redundant trunks with global reach, so you scale channels on demand without new physical circuits.
Which platforms do you support?
Microsoft Teams Direct Routing, Cisco Unified Communications Manager, Asterisk, FreeSWITCH, FreePBX, 3CX, Avaya, and the major hosted PBX and UCaaS platforms. We test compatibility before activation.
How many concurrent channels can I get?
From a handful to tens of thousands. Trunks burst on demand and we size accounts for real peak concurrency.

Let us price your traffic.

Send your top destinations and volumes. We reply the same business day with a rate card, a test trunk, and an SLA.
