[Stefan Reuter (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-16735?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=199908#comment-199908 ] 

Stefan Reuter commented on ASTERISK-16735:
------------------------------------------

Unfortunately what is currently implemented in 11.1.0-rc1 doesn't work with Polycom phones. Asterisk sends two NOTIFY messages where the first contains the incorrect caller ids followed by one with the correct ones. Polycom phones do not update the display however. See http://community.polycom.com/t5/VoIP/Busy-Lamp-Field-Caller-IDs-not-updated/td-p/24080

The following small patch for 11.1.0-rc1 prevents the first incorrect SIP NOTIFY message from being sent if notifycid is set:

> Enabling "notifycid" to "yes" is making asterisk to send NOTIFY information about callid in dialog-info section. In this dialog, asterisk also sends information about local and remote side. I found that data about remote side are the same as in the local side, witch is obviously wrong, according to RFC4235.
