[OpenSIPS-Users] MSILO can't send message

Thu Oct 14 02:03:28 EST 2021

Hi Bogdan-Andrei,

Finally made it send offline message by setting

modparam("msilo", "outbound_proxy", "sip:name.domain.com:5061
;transport=tls")
modparam("tls_mgm", "match_sip_domain", "[dom]*")

It seems the port number needs to be included and the match_sip_domain
needs to *. If the domain name is included, the error happens. Hope this
info is helpful for others who may be interested.

However, it still can't send the dumped message, but send "[Offline message
- Thu Jan  1 08:00:00 1970" no matter what the message is. It seems the
message was truncated. Based on the source code of the msilo module, the
message should be something like  "[Offline message - Thu Jan  1 08:00:00
1970] message here".

In the log, I can see the correct message was read out from the silo table.
Here is the log that shows the correct offline message that should be sent:

DBG:db_mysql:db_mysql_str2val: converting BLOB [{"type":"1","cont":"the
right message"}]

Thanks!
