    }
    ...
}
...

4.3.  sr_msg_async_pull(callid, msgid, gname, rname)

   Pull the message content and execute the route block 'rname' via async
   group 'gname'.

   This function can be used from ANY_ROUTE.

   Example 1.7. sr_msg_async_pull() usage
...
request_route {
    ...
    if(sr_msg_async_pull("$var(callid)", "$var(msgid)", "WG01", "REPOPULL")) {
    }
    ...
}
...

4.4.  sr_msg_rm(callid, msgid)

   Remove the message content.

   This function can be used from ANY_ROUTE.

   Example 1.8. sr_msg_rm() usage
...
request_route {

    if(sr_msg_rm("$var(callid)", "$var(msgid)")) {
    }
    ...
}
...

4.5.  sr_msg_check()

   Check if the message is stored.

   This function can be used from ANY_ROUTE.
