I am using ring_ready to let incoming calls to my IVR app ring couple times before the app engages:<div><br></div>session:execute(&quot;ring_ready&quot;);<br>session:sleep(8000);<br>...<br>session:answer();<div><br><div>On one of my servers I am using freeTDM to interface with Sangoma hardware, and another uses OpenZap (this is really the only difference between the two FS instances). Ringing/early media is playing on the openzap server, but not with freeTDM. Any idea why not?</div>
