 Posted: Mon Sep 01, 2008 12:05 pm Post subject: [Freeswitch-users] How to save RTP-audiostream to a file? |
 |
|
We had a question:
| Quote: | With which application and API is possible to keep full content of RTP audiostream to a file?
Our FreeSWITCH is configured in such manner that RTP-traffic directing throw FreeSWITCH,
but not between UAs.
|
And took answer on it:
-------------------------------------------------------------------
On it HELP we have mase such extension :
<extension name="ext-record">
<condition field="destination_number" expression="^4010$">
<action application="set" data="RECORD_TITLE=Recording ${destination_number} ${caller_id_number} ${strftime(%Y-%m-%d %H:%M)}"/>
<action application="set" data="RECORD_COPYRIGHT=(c) 2008, Altron Inc." />
<action application="set" data="RECORD_SOFTWARE=FreeSwitch" />
<action application="set" data="RECORD_ARTIST=Registration" />
<action application="set" data="RECORD_COMMENT=!!!" />
<action application="set" data="RECORD_DATE=${strftime(%Y-%m-%d %H:%M)}"/>
<action application="set" data="RECORD_STEREO=true"/>
<action application="record_session" data="$${base_dir}/recordings/${strftime(%Y-%m-%d-%H-%M-%S)}_${destination_number}_${caller_id_number}.wav"/>
<action application="set" data="ringback=${us-ring}"/>
<action application="bridge" data="sofia/nat/${dialed_ext}@localhost:5062 ([email]sofia/nat/@localhost:5062[/email])" />
<action application="answer" />
</condition>
</extension>
This draft works already, but there are new questions:
1. It's seems, that record of RTP session can occur only when RTP stream is routed through FS: UA-> FS-> UA, instead of directly (in LAN) UA-> UA.
For this purpose, as we understand, it is necessary to set values in variables of FreeSWITCH:
<action application="set" data="bypass_media=..."/>
<action application="set" data="proxy_media=..."/>
<action application="set" data="inbound_late_negotiation=..."/> ( for SIP profile nat for extension ext-record).
What values need to be set in variables that all RTP traffic passed through FreeSWITCH?
2. At extension ext-record we set record_session then we do bridge to leg B. As it is possible to configurate registration from another extension, for example:
<extension name="XXXX">
<condition field="destination_number" expression="^XXXX$">
...
<action application="execute_extension" data="ext-record XML public "/>
...
<action application="bridge" data="sofia/nat/YYYY" />
...
</condition>
</extension>
- where own extension not call any leg B, but only record session XXXX->YYYY.
How we are able to do this???
Thankful in advance, Evgeniy. |

Your questions are better suited for the users list. Please stop posting the same question to both lists.
