# What softswitches and SIP platforms are compatible with Cloud Softphone?

> Cloud Softphone connects to any standards-compliant SIP server. It registers like a normal SIP endpoint, so most deployments require zero custom integration. Full support for BroadSoft, Metaswitch, NetSapiens, 3CX, Asterisk, FreeSWITCH, and more.

**Cloud Softphone** connects to any standards-compliant **[SIP](/voip-glossary/sip/) server**. It registers like a normal SIP endpoint, so most deployments require zero custom integration. If your platform handles standard SIP registration and call signaling, Cloud Softphone will work.

## Softswitch Compatibility Matrix

  
    
      Softswitch / Platform
      Type
      Status
      Notes
    
  
  
    **BroadSoft / Cisco BroadWorks**Hosted PBXFull supportNative BroadWorks extensions for XSI directories, call center queues, and visual voicemail.
    **Metaswitch**Hosted PBXFull supportNative Metaswitch extensions. Ideal for operators stabilizing the app layer during a backend transition.
    **NetSapiens**Hosted PBXFull supportPresence integration via standard SIP SUBSCRIBE/NOTIFY.
    **Cisco Unified CM**On-prem PBXSupportedStandard SIP trunk registration.
    **Mitel**On-prem / Cloud PBXSupportedStandard SIP deployment model.
    **Sangoma**On-prem PBXSupportedStandard SIP registration.
    **3CX**Software PBXSupportedStandard SIP deployment model.
    **Asterisk / FreePBX**Open-source PBXSupportedStandard SIP registration. Widely deployed in custom voice environments.
    **FreeSWITCH**Open-source PBXSupportedAlso relevant for SDK and custom-build contexts.
    **Scratel**SIP ServerLikely compatibleStandard SIP protocol suggests compatibility. Verify feature-level behavior before deploying.
  

**Not on the list?** If your platform speaks standard SIP, it is a strong compatibility candidate. Request a demo to confirm your environment.

## What "Compatible" Means in Practice

Cloud Softphone is **[softswitch-agnostic](/blog/softphones/softswitch-agnostic-softphones/)**. The branded app is not locked to a single vendor. That gives operators three advantages:

  - **No rebuild on migration.** Switch from BroadSoft to Metaswitch (or the reverse) without rebuilding your subscriber app.

  - **Faster time to market.** Most deployments launch on standard SIP registration with no custom integration project.

  - **Feature parity depends on the platform.** If your softswitch exposes transfer, presence, voicemail, or BLF through standard SIP workflows, Cloud Softphone surfaces those features in the app.

[Provisioning](/resources/knowledge-base/provision-softphone-hundreds-users/) is handled through QR code, SMS link, web portal, or external API, so onboarding scales regardless of which softswitch sits underneath.

## Cross-Platform Support

Cloud Softphone deploys on **iOS**, **Android**, **Windows**, and **macOS** under a single branded service. Subscribers get a consistent experience across every device.
