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 version='1.0' ?><methodCall><methodName>pua.publish</methodName><params><param><value><string>sip:100-test@172.16.30.151</string></value></param><param><value><string>15</string></value></param><param><value><string>message-summary</string></value></param><param><value><string>application/simple-message-summary</string></value></param><param><value><string>.</string></value></param><param><value><string>.</string></value></param><param><value><string>sip:127.0.0.1:5060;transport=udp</string></value></param><param><value><string>Content-Length: 91</string></value></param><param><value><string>Messages-Waiting: yes

</string></value></param></params></methodCall>" http://172.16.30.151:5060/XML_RPC

Jan 24 12:05:07 test kamailio: 3(27128) ERROR: presence [publish.c:480]: ki_handle_publish_uri(): in event specific publish handling

For second I tried adding "\r" to to the end of each line:
# curl -H "Content-Type: text/xml" -X POST -d "<?xml version='1.0' ?><methodCall><methodName>pua.publish</methodName><params><param><value><string>sip:100-test@172.16.30.151</string></value></param><param><value><string>15</string></value></param><param><value><string>message-summary</string></value></param><param><value><string>application/simple-message-summary</string></value></param><param><value><string>.</string></value></param><param><value><string>.</string></value></param><param><value><string>sip:127.0.0.1:5060;transport=udp</string></value></param><param><value><string>Content-Length: 97</string></value></param><param><value><string>Messages-Waiting: yes\r

Thank you very much!

Hello,

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

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

Cheers,
Daniel

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
Voice-Message: 1/2

... debug output is:

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!
