When people call in (via callcentric) - they hear a stutter in the ringtone. My understanding is that the ringtone is generated by freeswitch - looks like here: <action application="set" data="transfer_ringback=${us-ring}"/> We are running the Debian release - 1.4.26~37-1~jessie+1 Could be this is a new 'feature'? Never sure. Anyone else seeing this? I'm thinking the ringtone might be using a different CODEX? -- -------------------------------------------------------------------------------- Karl Schmidt EMail Karl@xtronics.com Transtronics, Inc.
