[asterisk-bugs] [JIRA] (ASTERISK-24601) Missing tags in PJSIP NOTIFY dialog info

[Marco Paland (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-24601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=223966#comment-223966 ] 

Marco Paland commented on ASTERISK-24601:
-----------------------------------------

Okay, my configs are attached, complete pjsip.conf and dialplan hints (which are trivial).

The relevant standard is RFC 4235.
Part 4.1.1 describes the optional attrs. Snom phones need the "direction" attr ("initiator" or "recipient") among other things.
Part 4.1.6 describes the <local> and <remote> tags. These could be optionally invoked in chan_sip.

> I'm having a similar MAJOR issue, which makes 13.0.0 unusable with snom phones.
> We are using the PJSIP stack, not the chan_sip.
> The NOTIFY header (at ext 1010) of a ringing extension (1005) looks like:
> {code}
> <--- Transmitting SIP request (808 bytes) to UDP:192.168.1.155:36578 --->
> NOTIFY sip:1010 at 192.168.1.155:36578 SIP/2.0

> Issues:
> - <remote> and <local> tags of the dialog are missing completely
> - No (IMPORTANT) direction="recipient" attribute in <dialog> tag
> - entity="sip:1005 at 200.200.200.200:5060" is outside IP, but inside IP (192.168.1.1) is needed
> I had a short look in the actual res_pjsip_dialog_info_body_generator.c code and it seems that the first two points are missing.
> In 11.9.0 with chan_sip the NOTIFY dialog body looked like:
> {code}
> <?xml version="1.0"?>
