Seamless carrier integrations.
Any standard SIP trunk provider
Because the platform speaks standard SIP, the carrier is a configuration choice rather than a platform decision. Examples of providers our clients commonly run include:
Generic SIP Trunks
Any provider exposing a standard SIP interface — SIP host, auth credentials and codec negotiation. The primary and most flexible option.
Telnyx
A common trunk provider for voice and messaging, connected through your own account and API credentials under BYOC.
Bandwidth
Another widely used voice trunk provider. Routed through your account with your rates and contract — we take no position on it.
Your Own Carrier
Regional carriers, wholesale providers and direct agreements all work the same way. If it speaks SIP, it connects.
The providers named above are examples of commonly used trunk providers, not partnerships or endorsements. UDSOFTSOL does not resell connectivity and takes no margin on your carrier spend.
Credentials stay yours
Your trunk credentials live in your own tenant. You add the provider, the SIP host and the auth details; the platform takes it from there.
- Add a trunk and point it at your carrier's SIP endpoint
- Set your own rates, rate decks and termination rules
- Route by cost, quality or your own business rules
- Watch live trunk status and answer ratio in real time

The rest of your stack connects too
The carrier is one integration. Here's what else the platform talks to.
API & CRM Integration
REST API access and webhooks for provisioning, reporting and syncing customers into your CRM.
DID & Number Porting
Sell, assign, route, forward, bill and report on virtual numbers from an end-to-end DID platform.
PBX, IVR & Devices
SIP device support, PBX, IVR, calling card and call center add-ons for end-user deployments.
Payment Gateways
Automated invoicing, credit control and integration with the payment gateway your customers already use.
WebRTC & Custom Apps
Browser calling, video and messaging, plus custom modules, portals and automation built to your workflow.
Call Center Stack
Inbound and outbound campaigns, agent management, contact groups and live dashboards.
From trunk to traffic in four steps
Pick your carrier and open an account
You hold the contract, the rates and the relationship. We have no involvement in the commercial terms.
Add the trunk in your portal
Enter the SIP host and your own auth credentials. Nothing is shared with UDSOFTSOL.
Load your rate decks and routing rules
Set termination, cost, quality and least-cost routing using your own commercial data.
Point your traffic and go live
Provision SIP users or resellers, test with a test call, then cut over — with support alongside you.
Carrier responsibility stays with you
UDSOFTSOL supplies software. Your contract with your carrier, number provisioning, end-user KYC and regulatory filings are your obligations. Our compliance and responsibility statement sets this out in full.
