[OpenSIPS-Users] Doubt about call center module

[Daniel Zanutti]

Hi Bogdan

Yes, It's the same scenario and same message. The call flow is:

Asterisk Dials(port 5070) -> Opensips (port 5060) forward to Queue -> Calls
local user

I'm using standard Queue scenario:
<?xml version="1.0"?>
<scenario id="call center" name="Call center" param="1" type="script">
        <init>
                <bridge>
                        <server>
                                <id>server1</id>
                        </server>
                        <client>
                                <id>client1</id>
                                <type>message</type>
                                <destination>
                                        <value type="param">1</value>
                                </destination>
                        </client>
                </bridge>
                <state>1</state>
        </init>
</scenario>

And SIP message is the same on all calls, just changed Call-id/tags:

U 10.10.10.10:5070 -> 10.10.10.10:5060
INVITE sip:fila-1 at 10.10.10.10:5060 SIP/2.0.

I updated to latest 2.4.2 GIT version (commit
8b6830cdd96298682fcc298095ad1b718c54c77d), same problem is happening.

Also you can access the server if you want, it's dedicated to this test.

Thanks
