[Freeswitch-users] [Linphone-developers] comfort noise and opus

[Dragos Oancea]

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 .
Cheers,Dragos

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 reproduceplace a call with linphone using opus to a freeswitch server voicemail extension.listen to the outgoing message and leave a voicemail after the prompt.
observedFairly loud comfort noise is heard while leaving the message.
expectedshould 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.
workaroundadd this to the voicemail extension before the answer application. <action application="set" data="record_waste_resources=true" ></action>
Sincerely,
Russell Treleaven
