Generic SIP Settings for 2talk

If your device is not listed in our user guides then you can usually register any generic SIP v2 compliant devices with just a few basic settings.

Generic Settings for 2talk

  • Login/Username/ID: your-2talk-number
  • Authorisation Username/ID: your-2talk-number
  • Password: your-2talk-password
  • Domain/Realm: sip.2talk.co.nz
  • Proxy: sip.2talk.co.nz
  • Outbound Proxy: sip.2talk.co.nz
  • Use Outbound Proxy: yes
  • Register Expires: 600
  • DMTF Mode: RFC2833 (or AVT/out of band)
  • Port ranges are
    UDP 20000-50000  for RTP
    UDP/TCP 5060,5061,50600 for SIP

The DTMF mode should be 'inband' in the case where fax machines or alarm systems are being used. There are other settings that can be configured but may differ from device to device on how these are implemented, but in general terms we usually advise customers set the following:

  • Preferred Codec: G.711a (or alaw)
  • Secondary Codec: G.711u (or ulaw)
  • Other default supported codecs: G.722, G.729a, GSM
  • T.38 support: Enabled (for fax machines or alarms)
  • Echo cancelation: Enabled (except for fax machines or alarms)
  • Silence Suppression or VAD: Disabled
