[Freeswitch-users] SIP dialin not working

[Markus Heller]

Dear list,

I am trying to configure SIP dialin. I can call my freeswitch/BBB
server. It does execute the "play_and_get_digits", I can enter the PIN
number of my conference which I can now see in my BBB GUI, but then I
get a HANGUP.

fs_clibbb tells me, when the call comes in:

After entering the PIN number (DTMF decode works fine): 

EXECUTE [depth=0] sofia/external/[callernumber]@sip.[xyz].com
transfer(SEND_TO_CONFERENCE XML default)
... switch_ivr.c:2243 ... State Change CS_EXECUTE -> CS_ROUTING
switch_ivr.c:2250 Transfer sofia/external/[callernumber]@sip.[xyz].com
to XML[SEND_TO_CONFERENCE at default]
... some more lines that don't look conspicuous...

mod_dialplan_xml.c:637 Processing [callernumber] <[callernumber]>-
>SEND_TO_CONFERENCE in context default

Then there is a Dialplan block that does not terminate properly:

Dialplan: sofia/external/[callernumber]@sip.[xyz].com parsing [default-
>unloop] continue=false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com Regex (PASS)
[unloop] ${unroll_loops}(true) =~ /^true$/ break=on-false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com Regex (FAIL)
[unloop] ${sip_looped_call}() =~ /^true$/ break=on-false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com parsing [default-
>bbb_conferences_ws] continue=false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com Regex (FAIL)
[bbb_conferences_ws] ${bbb_authorized}() =~ /true/ break=on-false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com parsing [default-
>bbb_conferences] continue=false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com Regex (FAIL)
[bbb_conferences] ${bbb_authorized}() =~ /true/ break=on-false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com parsing [default-
>bbb_echo_test_direct] continue=false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com Regex (FAIL)
[bbb_echo_test_direct] ${bbb_authorized}() =~ /true/ break=on-false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com parsing [default-
>ECHO_TO_CONFERENCE] continue=false
Dialplan: sofia/external/[callernumber]@sip.[xyz].com Regex (FAIL)
[ECHO_TO_CONFERENCE] ${bbb_from_echo}() =~ /true/ break=on-false

Ending up in:

2020-12-11 10:16:01.332329 [INFO] switch_core_state_machine.c:312 No
Route, Aborting

With a final statement:

2020-12-11 10:16:01.332329 [NOTICE] switch_core_state_machine.c:313
Hangup sofia/external/[callernumber]@sip.[xyz].com [CS_ROUTING]
[NO_ROUTE_DESTINATION]

I understand that the Regex checks try to match the extension names in
the three files in /opt/freeswitch/conf/dialplan/default.

Probably, the call should match with "bbb_conferences", where the Regex
fails with "not authorized". This is strange, because I am explicitly
using an "authorized" statement in my dialin.xml config file:

>>>>>
<extension name="check_if_conference_active">
 <condition field="${conference ${pin} list}" expression="/sofia/g" />
 <condition field="destination_number"
expression="^SEND_TO_CONFERENCE$">
   <action application="set" data="bbb_authorized=true"/>
   <action application="transfer" data="${pin} XML default"/>
 </condition>
</extension>
<<<<<

I think I fail to understand something right in front of me :-)

Please help.

Thanks a lot in advance!
