[asterisk-bugs] [JIRA] (ASTERISK-20709) Asterisk sends wrong Caller IDs in first SIP NOTIFY message

[Daniel Kerr (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20709?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=211767#comment-211767 ] 

Daniel Kerr commented on ASTERISK-20709:
----------------------------------------

I'm seeing this issue too.

In my case its intermittent, roughly half the time the incorrect notify doesn't get sent. My suspicion is that in those cases the call has progressed sufficiently such that the callee information is available and included.

> The fix for ASTERISK-16735 does not work with Polycom phones. Asterisk sends the wrong Caller IDs with the first SIP NOTIFY message and follows up with a seconds message with the correct Caller IDs. Polycom phones do not update the display and continue to show the wrong Caller IDs from the first message.
> First SIP NOTIFY message conatins wrong remote and local identity (both extension/address of called phone):
> {code}
> <remote>
> <identity display="1202">sip:1202 at reucon.com</identity>
> <target uri="sip:1202 at reucon.com"/>
> </remote>
> <local>
> <identity display="1202">sip:1202 at reucon.com</identity>
> <target uri="sip:1202 at reucon.com"/>
> </local>
> {code}
> Second SIP NOTIFY message contains correct remote and local identity:
> {code}
> <remote>
> <identity display="Stefan Reuter">sip:1201 at reucon.com</identity>
> <target uri="sip:1201 at reucon.com"/>
> </remote>
> <local>
> <identity display="phone-02">sip:1202 at reucon.com</identity>
> <target uri="sip:1202 at reucon.com"/>
> </local>
> {code}
> See attached pcap file.
