SIP Provider: Breezz

The provider was tested by our Belgian partner Com8.

Please note that not all possible scenarios have been tested, for example Fax via T.38. However it might be still interesting for you to know which features to expect when using this provider. Breezz offers as alternative to Fax via T.38 a fax-to-email solution. Playing Music on Hold from the PBX may be possible, the configuration-website of this account, has normally some options relating MoH. However this was not possible with the test-account used.

  • Features:
    • Direct Dial In
    • DTMF
  • Supported Codecs by the provider
    • G711
    • G729
    • G723
