By default, SIP calls will be presented to your SIP servers with the G.711 audio codec as the suggested default.<\/strong><\/p>\n

Recommended Codecs<\/h2>\n

If your SIP equipment allows you to set supported audio codecs, we recommend that you only enable the following:<\/p>\n

\n
• G.711 A-law<\/span><\/li>\n
• G.711 U-law<\/span><\/li>\n
• G.729<\/span><\/li>\n<\/ul>\n

  Other Supported Codecs<\/h2>\n

  Our system also supports the following codecs \u2013 though these have not been thoroughly tested.<\/p>\n

  \n
  • L16<\/span><\/li>\n
  • GSM<\/span><\/li>\n
  • Speex<\/span><\/li>\n
  • iLBC<\/span><\/li>\n<\/ul>\n
    Phone numbers purchased from our old provider (before December-2018) only support G.711 A-law\/U-law and G.729 for incoming calls.<\/div>\n
