[SR-Users] presence_mwi body check problem

Thu Jan 24 19:35:41 CET 2019

Hello again,

I updated my system with latest version of Kamailio from master branch.
Attached file was generated with your suggestion. This time I used Postman
instead of curl.

Here is the output from debug:

*Jan 24 19:36:21 geo-location1-manager1 kamailio: 3(29836) ERROR:
presence_mwi [add_events.c:110]: mwi_publ_handl(): check of body
<Messages-Waiting: yes*
*Jan 24 19:36:21 geo-location1-manager1 kamailio: Message-Account:

*Jan 24 19:36:21 geo-location1-manager1 kamailio: Voice-Message: 1/2 (0/0)*
*Jan 24 19:36:21 geo-location1-manager1 kamailio: > failed at character
index 22 (hexa: 0xa)*
*Jan 24 19:36:21 geo-location1-manager1 kamailio: 3(29836) ERROR: presence
[publish.c:419]: ki_handle_publish_uri(): in event specific publish
handling*

Thank you very much!
