Frequently asked questions

VoipMS Desktop is a Windows app for SIP calling, SMS/MMS, contacts, call history, and voicemail against your existing VoIP.ms account. It is not a carrier — VoIP.ms still bills minutes and messages.

The current release is a Windows desktop client. Additional operating systems may follow. You need an active VoIP.ms account with SIP and (for messaging) API access enabled.

No. After you save API and SIP credentials in Settings, the app talks directly to VoIP.ms. Keep the portal for billing, DID ordering, and account-level options.

Point the client at a VoIP.ms POP (vancouver.voip.ms, toronto.voip.ms, and others), enter the SIP username and password for your sub-account, and register. Inbound ringing and outbound dialing use that registration.

Messaging uses the VoIP.ms REST API with the credentials you store locally. Threads, attachments, and delivery status stay in the desktop inbox. Carrier filtering and 10DLC rules still apply on the VoIP.ms side.

API and SIP secrets stay on your machine. voipmsdesk.com accounts are for licensing the software, not for proxying your VoIP.ms password through our servers.

Licenses are SMS+, Voice+, or Pro, billed monthly or yearly. One Windows seat is included; extra seats are $5/mo or $50/yr. See Pricing.

New accounts can start a 7-day trial after signup. Once we exit preview, paid plans are required to keep a license active.

Sign in, open your account, and choose Cancel trial / manage billing. That opens Stripe’s billing page where you can end the subscription. If you cancel before the trial ends, you are not charged. You can also use the Contact page.
