Subject: res_pjsip_dialog_info_body_generator: Set LOCAL target URI as local URI
X-Git-Tag: 16.27.0-rc1~18
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ec5eb5ae66871d99feb93a3dd4d371f62e40642;p=thirdparty%2Fasterisk.git

res_pjsip_dialog_info_body_generator: Set LOCAL target URI as local URI

The change "Add LOCAL/REMOTE tags in dialog-info+xml" set both "local"
Identity Element URI and Target Element URI to the same value -
the channel Caller Number.
For Identity Element it's ok to set as Caller ID.
But Local Target URI should be set as local URI.

In this case the Local Target URI can be used for Directed Call Pickup
by Polycom ip-phones (parameter useLocalTargetUriforLegacyPickup).

Also XML sanitized Display names.

ASTERISK-24601
