[Spce-user] SIP "MESSAGE" to offline user

[andreas tseiko]

Dear Andrew,
Dear Andrew,

 

According to
your recommendations we have inserted the following configuration lines into
file  /etc/ngcp-config/templates/etc/kamailio/proxy
“kamailio.cfg.tt2”.

Nevertheless
messages cannot be stored in silo db table and though cannot be sent to sub
when he will be back on line.

Do we need
something more?

 

loadmodule
"msilo.so"

 

#!ifdef
WITH_MSILO

modparam("msilo","db_url","mysql://[%
kamailio.proxy.dbrwuser %]:[% kamailio.proxy.dbrwpw %]@[% database.dbhost %]/[%
kamailio.proxy.dbname %]")

modparam("msilo",
"db_table", "silo")

modparam("msilo","from_address","sip:registrar at xxxxxxx.local")

modparam("msilo",
"from_address", "sip:$rU at xxxxxxx.local")

modparam("msilo","contact_hdr","Contact:
<sip:registrar at xx.xx.xx.xx:5062>;msilo=yes\r\n")

modparam("msilo","content_type_hdr","Content-Type:
text/plain\r\n")

modparam("msilo","offline_message","***
User $rU is offline!")

#!endif

 

modparam("usrloc",
"db_mode", 0) initial value was “1”
