Dear Team,

I have added traces via pasetbin

MESSAGE Stored When B is OffLine https://pastebin.com/NLwMePmf

[trace screenshot removed]

Next this messages should be delivered when B party REGISTER with the server

Issue 1: Message was delivered to B-party but it didn't remove form DB and as a result MESSAGE deliver to B-party as many times it come line  https://pastebin.com/7pb0wCKx
[trace screenshot removed]
​

Now next issue is

Issue 2: Messages deliver to B-party when its already online without storing in DB. B-party receive MESSAGE successfully but A-party gets MESSAGE delivery failed.

https://pastebin.com/zgDbK4F6

[trace screenshot removed]
​

I intentionally modified the 202 - description for better troubleshooting.

See if attachments were received properly through mailing list.

For convenience I have attached the pcap as well.

MESSAGE: 1: Accepted and Stored as expected
MESSAGE: 2: Server delivered Message when B comes online
MESSAGE: 3: Both A & B are online. A-party receives MESSAGE delivery failure where as B-party receives MESSAGE successfully

Modified default kamailio.cfg is https://pastebin.com/thZig5RC

It looks that mingled up the configuration.

Please see whats gone wrong here.

Dear team,

Thank you for your reply.

@MS & @ Davld, Let me test again and share traces.

@Zaka, I will check the save() result as you suggested. Location is being saved and properly looked up because messages are being delivered (and not stored in DB ) when both parties are online.

Please check the return value of save and replace the logic: -

 

$var(save_result) = save("location") ;

if ($var(save_result) <= -1) {

    xlogl("L_ERROR", "[$rm] -> Unable to save user location \n");
    sl_reply_error();

     exit();

}

 

 

if ($var(save_result) == 1) {

    xlogl("L_INFO", "[$rm] -> dumping messages with MSILO \n");
    # MSILO - dumping user's offline messages to user
    if (m_dump("$fu")) {
         xlogl("L_NOTICE", "MSILO: offline messages for $fu dumped - if they were \n");
    }
    else {
         xlogl("L_NOTICE", "MSILO: no offline messages dumped \n");
     };
}

 

This means dump the message only when it is not re-registration.

 

Thanks

Hi team,

I am facing an issue while setting up IM server based on kamailio.

SIP-SIP online messaging is fine. For offline messaging i am using msilo module which is storing offline messages in 'silo' table.

 

As B-party come online ... it receive offline messages stored in database. But 

Problem is.. these messages will deliver to B-party as many time it REGISTER online.

 

How can I configure msilo module to mark messages delivery status?
or how can i delete the delivered messages so that there will be no chance of delivering them again on next REGISTER?

Message parts of kamailio.cfg are
....
/* add local domain aliases */
alias="192.168.10.18"
