Which SIP settings receive calls to my DID?

Your DID delivers calls to your FreeVoIP account, so the handset or app that answers must be registered with these details:

• SIP server / proxy / domain: sip.transcom.net
• User ID: your account username (for example 158461_myoffice)
• Password: your account password
• Port: 5060 (UDP) or 5061 (TLS)

Enter these into any SIP desk phone, softphone or mobile app. On Windows, the quickest route is My Account → My VoIP → Lines → Windows phone, which downloads a MicroSIP bundle with everything pre-filled. Once the device shows as registered, calls to your DID will ring it.
