> 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}

> 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:
