As per my post on the cisco forums ... https://supportforums.cisco.com/thread/2052011
can anyone in the freeswitch community help me here.

Im using a SPA525g ( with SPA500s ) registered to Freeswitch.
Im trying to use BLF on the sidecart with this configuration
 
<Server_Type group="Att_Console/General">Broadsoft</Server_Type>
<Unit_1_Key_1 group="Att_Console/Unit_1">fnc=sd+cp+blf;sub=99007@10.12.253.10</Unit_1_Key_1>
<Unit_1_Key_2 group="Att_Console/Unit_1">fnc=cp+blf;sub=99007@10.12.253.10</Unit_1_Key_2>
<Unit_1_Key_3 group="Att_Console/Unit_1">fnc=blf;sub=99007@10.12.253.10</Unit_1_Key_3>
<Unit_1_Key_4 group="Att_Console/Unit_1">fnc=sd;sub=99007@10.12.253.10</Unit_1_Key_4>
<Unit_1_Key_5 group="Att_Console/Unit_1">fnc=blf+sd;sub=99007@10.12.253.10</Unit_1_Key_5>
<Unit_1_Key_6 group="Att_Console/Unit_1">fnc=blf+sd;sub=99007@10.12.253.10;ext=99007@10.12.253.10</Unit_1_Key_6>
<Unit_1_Key_7 group="Att_Console/Unit_1">fnc=blf+sd+cp;sub=99007@10.12.253.10</Unit_1_Key_7>
<Unit_1_Key_8 group="Att_Console/Unit_1">fnc=blf+sd+cp;sub=99007@$PROXY</Unit_1_Key_8>
 
All keys flash orange except Key_4 ( which is simply a speed dial )

I can see freeswitch accepting my SIP SUBSCRIBE   ( With - SIP/2.0 202 Accepted )
and then sending me SIP NOTIFY Messages ( to which the 525g responds SIP/2.0 200 OK )

however the lights continue to flash orange.

in my SIP Profile I DO have 
    <param name="manage-presence" value="true"/>
    <param name="manage-shared-appearance" value="true"/>

and also 
    <param name="dbname" value="my-shared-db_presence"/>
    <param name="presence-hosts" value="$${domain}"/>

but this dosnt look to me like its a freeswitch config issue, since the pcap shows FS Sending NOTIFIES.
( please can someone confirm this looks ok from the freeswitch side )

please can someone point me in the right direction here, Id love to know whats wrong.
 
PLEASE Find attached the gzipped pcap.
