Early media and PRACK support

Last Updated : Oct 12, 2014 |
IP Office supports in-band announcements such as:
  • Branding from discount or bulk long distance providers

  • Progress indications when extraordinary wait times are inherent in the call scenario, for example when trying to locate a cell phone

  • Country-specific ring back and other progress tones

  • Conferencing in the IP domain before call answer, for example, in call recording scenarios or for automatic dialers' conferencing in agents

Implementation engineers can configure SIP trunks to support early media by adding the 100rel to Supported header in the INVITE parameter.
