[Freeswitch-users] SCA not working inbound - Multi Domain

25 May 2012

      Hi all,

I have a muti-tennnant configuration that is working nicely except for
Shared Call Appearance.  The desktop devices are CISCO 504Gs and they are
configured as described in the FS Wiki as well as Cisco Documentation.

The SCA works perfectly for outbound calls - if either phone pickups like
220, the other phones indicator light flashes red.  However, inbound calls
will go to only one of the phones (which one has changed a few times) and
the other phones line still just stays green and does not ring.

Here is the sip interfaces config:

<profile name="internal">

    <settings>

      <param name="enable-timer" value="false"/>

      <param name="user-agent-string" value="Configured by Sean!"/>

      <param name="rtp-timer-name" value="soft"/>

      <param name="codec-prefs" value="$${global_codec_prefs}"/>

      <param name="manage-shared-appearance" value="true"/>

      <param name="multiple-registrations" value="true"/>

      <param name="manage-presence" value="true"/>

      <param name="inbound-codec-negotiation" value="generous"/>

      <param name="inbound-reg-force-matching-username" value="true"/>

      <param name="nonce-ttl" value="86400"/>

      <param name="rfc2833-pt" value="101"/>

      <param name="manage-presence" value="true"/>

      <param name="auth-calls" value="true"/>

      <param name="sip-ip" value="10.10.40.185"/>

      <param name="rtp-ip" value="10.10.40.185"/>

      <param name="sip-port" value="5064"/>

      <param name="nat-options-ping" value="false"/>

      <param name="all-reg-options-ping" value="true"/>

      <param name="context" value="from-BFIS"/>

    </settings>

  </profile>

The directory entry which both phones connect using:

    <user id="220">

      <variables>

        <variable name="outbound_caller_id_name" value="BFIS Sean"/>

        <variable name="outbound_caller_id_number" value="410420BLEEP"/>

        <variable name="internal_caller_id_name" value="Sean BLEEP"/>

        <variable name="internal_caller_id_number" value="220"/>

        <variable name="user_context" value="from-internal-BFIS"/>

        <variable name="user_originated" value="true"/>

        <variable name="toll_allow" value="domestic"/>

        <variable name="accountcode" value="220"/>

        <variable name="mwi-account" value="220@voicemail_BFIS"/>

      </variables>

      <params>

        <param name="manage-shared-appearance" value-="true" />"

        <param name="password"  value="BLEEPBLEEP"/>

        <param name="dial-string"
value="{presence_id=220@mydomainname.com}${sofia_contact(220@mydomainname.co
m)}"/>

        <param name="mwi-account" value="220@voicemail_BFIS"/>

      </params>

    </user>

And the dial plan for ext 220:

  <extension name="220" >

    <condition field="destination_number" expression="^220$">

      <action application="set"
data="effective_caller_id_number=${internal_caller_id_number}"/>

      <action application="set"
data="effective_caller_id_name=${internal_caller_id_name}"/>

      <action application="set" data="ringback=${us-ring}"/>

      <action application="set" data="call_timeout=20"/>

      <action application="set" data="hangup_after_bridge=true"/>

      <action application="bridge"
data="{sip_invite_domain=mydomainname.com}user/220@mydomainname.com"  /> 

      <action application="answer"/>

      <action application="voicemail" data="default voicemail_BFIS 220"/>

      <action application="hangup"/>

    </condition>

  </extension>

I did see this in the wiki
(http://wiki.freeswitch.org/wiki/Shared_Line_Appearance):

If SLA works for outgoing calls and SLA does not work for inbound calls to
the SLA phones, you may have some presence problem related to mixed IP and
domain names. When using ODBC you may issue the following SQL statement

select
sip_to_host,sip_from_user,sip_from_host,hostname,presence_id,call_info from
sip_dialogs;

But I don't have ODBC on this server, so I am a little lost.

I have the phones login to domain names, not addresses.  I never refer to IP
addresses in my xml (except gateways addresses).  I am not trying SLA across
domain, only within the same domain.

I hope someone can spot something.  Thanks for your help.
