[SR-Users] OPTION pings with dispatcher to asterisk box

Hi Henning,
i assume that the example of the dispatcher.list is portable to any sql
based dispatcher szenario.
Tried code=401 (was not working) and now class=4.
So now i am thinking, that is *never* possible to overwrite or add
class/code szenarios for dispatcher targets.
And with that in mind, the module documentation with the "class=4" entry in
dispatcher.list file is WRONG.
Tried that:
"SET": {
"ID": 1200,
"TARGETS": [{
"DEST": {
"URI": "sip:TRUNK.DNSNAME.EXAMPLE;transport=tls",
"FLAGS": "IP",
"PRIORITY": 0,
"ATTRS": {
"BODY":
"socket=tls:XX.XX.XX.XX:5061;ping_from=sip:TRUNK.DNSNAME.EXAMPLE;class=4",
"DUID": "",
"MAXLOAD": 0,
"WEIGHT": 0,
"RWEIGHT": 0,
"SOCKET": "tls:XX.XX.XX.XX:5061"
},
"LATENCY": {
"AVG": 22.099998,
"STD": 2.514403,
"EST": 22.099998,
"MAX": 27,
"TIMEOUT": 0
}
}
}]
}
}]
Cheers Karsten
