Re: [SR-Users] presence_mwi body check problem

Hello,

I am not sure if curl is converting \r into the single corresponding char. Can you try to write the xml in a file, where you ensure the \r\n are the corresponding chars -- one option would be to do it with echo, like:

echo -e "first line\r\nsecond line\r\n..." >/tmp/data.xml

and then use curl with the parameter to read data from file.

I also pushed a small patch to master branch that is printing the hexa code of the character which is wrong, so should be easier to troubleshoot -- maybe you can test with it.

Cheers, Daniel

Hello Daniel,

According to Wireshark they are. I attached packet pactures for two attempts. Hope they will help to identify the problem. First one has "\n" and second "\r\n"

First PUBLISH was generated by pua.publish like so:

/# curl -H "Content-Type: text/xml" -X POST -d "<?xml

For second I tried adding "\r" to to the end of each line:

/# curl -H "Content-Type: text/xml" -X POST -d "<?xml

Hello,

are the lines ended by \r\n? Like:

/Messages-Waiting: yes\r\n.../

Cheers,

Hello!

I'm trying to process PUBLISH on Kamailio (v. 5.2.1) but
constantly getting "500 Server Internal Error" responce.

For packet body:

    /Messages-Waiting: yes/
    /Message-Account: sip:100-test@172.16.30.151
    <mailto:sip%3A100-test@172.16.30.151>/
    /Voice-Message: 1/2/
    /
    /

... debug output is:

    /kamailio: 2(27127) DEBUG: presence [event_list.c:348]:

    /
    /

I'm not sure, but it appears to me that check in line 95
from https://github.com/kamailio/kamailio/blob/5.2/src/modules/presence_mwi/add_events.c
is not passing. I was trying to add "\n" and "\r" to the end of
each string but I always had failure on character number 22.

Does anyone know how exactly PUBLISH packet body should look like?

Thanks a lot!
