Re: [OpenSIPS-Users] Drop the call from onreply_route with cause code

[Mehdi Shirazi]

Thanks Ben for your reply.
It seems there is one way to cancel initiated call from reply_route:

onreply_route[3] {
...
if ($hdr(User-Agent)=~"Snom") {
# drop calls involving snom UA
t_cancel_branch();
}
...
}

*Hi Alexey*

*Thanks for the reply, so how can we read a reply message(even outside
reply_route) and based on the information in it, decide to send a
reply with special cause code and terminate the initiated call ? *

[OpenSIPS-Users] SQL Cacher+Galera Cluster

[Mehdi Shirazi]

Hi
I plan to use SQL Cacher with Galera Cluster. After a record changes I want
to update the cache. Using standard triggers in mariadb is not possible to
run opensips-cli commands.
Please tell me your suggestions for the best approach.

[OpenSIPS-Users] SQL Cacher full caching auto reload specific key

[Mehdi Shirazi]

Hi
I use SQL Cacher in full caching mode. when the database changes I want to
automatically reload that specific key.
What is your suggestions for this?
With Mariadb trigger I cannot use system commands to reload that specific
key. Only way is using pooling method of changed records and use
sql_cacher_reload
?

Re: [OpenSIPS-Users] Opensips 3.1 Play Media

[Mehdi Shirazi]

Hi Dhaval
Usually for using rtpengine_play_media we need A and B party,B party
generates Reply and SDP.

If you want to omit B party you should generate Reply and SDP inside
script. please see the workaround mentioned here[1]

and also this feature request[2].
[1] https://github.com/sipwise/rtpengine/issues/870

[2] https://github.com/OpenSIPS/opensips/issues/1996

I do not know exact final script but working on it.

Re: [OpenSIPS-Users] OpenSIPS 3.1 Media Bridging Feature

[Mehdi Shirazi]

Hi
Not sure this is in scope of new module ... with rtpengine_play_medi added
in 3.1 it is possible to play media to one of the endpoints, but I like to
use Opensips+rtpengine as an end point playing music for caller. it seems
now there is need for some signaling generated from Opensips (like 183...)
to make it possible to use this function when there is no B party.

[OpenSIPS-Users] opensip 3.1 rtpengine_play_media

[Mehdi Shirazi]

Hi
I am trying to use rtpengine_play_media in opensips 3.1
If I use :
if (is_method("INVITE") && !has_totag())
rtpengine_play_media("file=/path/to/ringback_tone_file.wav");

I receive error about no call ID. If I add
rtpengine_manage(); before rtpengine_play_media functions it

seems(in logs) rtpengine side is ok but still cannot hear wav file.

I should also send 183/sdp myself or it is automatic?

Is it possible to provide a working sample of playing a file for all
incoming calls?
