I noticed something that I thought I would share for the benefit of others. FreeSWITCH Version 1.5.15b+git~20141215T224714Z~0b414a8de8~64bit (git 0b414a8 2014-12-15 22:47:14Z 64bit) Linphone 3.9.1 To reproduce place a call with linphone using opus to a freeswitch server voicemail extension. listen to the outgoing message and leave a voicemail after the prompt. observed Fairly loud comfort noise is heard while leaving the message. expected should hear silence instead of comfort noise. If we change the codec to pcmu we hear silence instead of comfort noise. Comfort noise is heard because after the outgoing message freeswitch stops sending rtp. workaround add this to the voicemail extension before the answer application. <action application="set" data="record_waste_resources=true"

This is quite old FreeSWITCH code, almost 2 years old. We’ve done significant work on opus support since then, i would start before you make any assumptions switching to the latest release 1.6.10.

Hi Try Freeswitch 1.6.x - preferably 1.6.10 - lots of things changed since 1.5.x . Freeswitch and Linphone work pretty good together when it comes to Opus .
