Using Session Initiation Protocol

If you are using a SIP software phone, you must specify the SIP address of your Voice Server software (not Portal Server software). Use the following URL format:

sip://vws@voiceserver.example.com:5060

Where vws means “access the Nuance Voice Web Server service” on the server named voiceserver.example.com, and 5060 is the port that Nuance Voice Web Server is listening on for SIP connection requests.
