Rusty Newton updated ASTERISK-27224:
------------------------------------

    Assignee: Richard Kenner  (was: Unassigned)
      Status: Waiting for Feedback  (was: Triage)

Do you have an Asterisk log showing what was happening at the time? Hopefully one with high verbosity or debug.

Also, can you provide sanitized Asterisk configuration? Preferably for your SIP channel driver, RTP configuration and anything else relevant.
