[dpa-freeswitch at aege...]

Hello,

I want to call from Linphone on Android to Gnome Calls. The SIP trace
can be found at https://gitlab.gnome.org/GNOME/calls/-/issues/434 .
Linphone announces OPUS. FreeSWITCH is supposed to do transcoding
between codecs. It proposes however to Gnome Calls only OPUS as viable
protocol. Gnome Calls rejects the INVITATION, as it does not speak
OPUS.

I the SIP profile I have

<param name="inbound-codec-prefs"
value="OPUS,G722,PCMU,PCMA,H264,VP8"/>
<param name="outbound-codec-prefs"
value="OPUS,G722,PCMU,PCMA,H264,VP8"/>

While calling, the variable ep_codec_string has the value
mod_opus.opus@48000h@20i@2c,CORE_PCM_MODULE.PCMU@8000h@20i@64000b,CORE_PCM_MODULE.PCMA@8000h
@20i@64000b,mod_spandsp.G722@8000h@20i@64000b.

I have enabled Late Negotiation.

FreeSwith offers only OPUS to Gnome Calls and the latter rejects the
connection.

The question is, why doesn't FreeSwitch offer transcoding, and the
PCMA+PCMU codecs to the callee?




I have one more question. I want to execute some actions
unconditionally in a dialplan, in particular to record all calls.

I do:


<context name="default">
<extension name="recording" continue="true">
<condition break='never' >
<anti-action application="set" data="record_sample_rate=32000"/>
<anti-action application="record_session"
data="$${recordings_dir}/B-${strftime(%Y-%m-%d-%H-%M-
%S)}_${destination_number}_${caller_id_number}.wav"/>

<action application="set" data="record_sample_rate=32000"/>
<action application="record_session" data="$${recordings_dir}/A-
${strftime(%Y-%m-%d-%H-%M-
%S)}_${destination_number}_${caller_id_number}.wav"/>
</condition>
</extension>
<!-- other extensions -->
</context>

It does work, but sometimes the action is executed, sometimes the anti-
action. ( I hope I say the truth, since I made a lot of changes
recently and these are the results I remember).

Is there any way to execute a condition unconditionally, or rather to
execute actions outside of a condition and extension? Here, to record
all calls, without having an extension/condition?

Thanks in advance for your ideas!

Greetings
Дилян
