[Michael L. Young (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=200193#comment-200193 ] 

Michael L. Young commented on ASTERISK-20748:
---------------------------------------------

What kind of "pbx phone" are you using?  SIP phone?

If SIP, please also attach a pcap of the communication between the phone and the PBX.

We require a complete debug log to help triage the issue. This document will provide instructions on how to collect debugging logs from an Asterisk machine for the purpose of helping bug marshals troubleshoot an issue: https://wiki.asterisk.org/wiki/display/AST/Collecting+Debug+Information
