[SR-Users] presence_mwi body check problem

Thu Jan 24 11:25:10 CET 2019

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 at 172.16.30.151
<sip%3A100-test at 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*
*Message-Account: sip:100-test at 172.16.30.151 <sip%3A100-test at 172.16.30.151>*
*Voice-Message: 1/2 (0/0)*
*</string></value></param></params></methodCall>"

*Jan 24 12:05:07 test kamailio: 3(27128) ERROR: presence_mwi

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 at 172.16.30.151

Thank you very much!
