[Freeswitch-users] 183 and no ringback when send_silence_when_idle is non-zero

[Phil Quesinberry]

Ok. more info on this.

In default Proxy-Media mode:
When making a call through the gateway for PSTN termination, FS sends 180 -
Ringing to the calling endpoint when 'send_silence_when_idle' is set to 0
and ringback tone is heard.  FS sends 183 and early media to the calling
endpoint when 'send_silence_when_idle' is set to a non-zero value and no
ringback tone is heard.

In Bypass-Media mode:
Making that same call through the gateway, FS sends 180 - Ringing to the
calling endpoint regardless of the 'send_silence_when_idle' value and
ringback tone is heard.

Is this the intended behavior?

- Phil

Actually it's one of the latest 1.2.0 revisions - b653c21.

I didn't realize that with the quick look I had at the code.  Curious. that
makes me wonder if the Aastra phones are generating the noise when they
don't see any media.  A user complained about hearing the noise when first
logging into voicemail, before she is asked for her PIN.  I hadn't noticed
it before because I normally do that on speaker but on the handset, it is
quite noticeable.

Is there a way to use send_silence_when_idle without having it kill ringback
when set to a non-zero value?

Which revision of the code are you looking at?
The sleep sends dummy frames unless you set that
send_silence_when_idle var, if its not set its probably not sending
anything.
You can see in the code that unless that var is set it wont be
generating anything.
