[SR-Users] presence_mwi body check problem

[Володимир Іванець]

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 at 172.16.30.151 <sip%3A100-test at 172.16.30.151>*
*Voice-Message: 1/2*

... debug output is:

*kamailio: 2(27127) DEBUG: presence [event_list.c:348]: search_event():
start event= [message-summary/6]*
*kamailio: 2(27127) DEBUG: presence [publish.c:351]:
ki_handle_publish_uri(): SIP-If-Match header not found*
*kamailio: 2(27127) DEBUG: presence [presentity.c:88]: generate_ETag():

*kamailio: 2(27127) DEBUG: presence [publish.c:385]:

*kamailio: 2(27127) ERROR: presence_mwi [add_events.c:110]:

*kamailio: Message-Account: sip:100-test at 172.16.30.151
<sip%3A100-test at 172.16.30.151>*
*kamailio: Voice-Message: 1/2*
*kamailio: > failed at character number 22*
*kamailio: 2(27127) ERROR: presence [publish.c:480]:
ki_handle_publish_uri(): in event specific publish handling*

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!
