[Freeswitch-users] Dialplan sip chat with SIPml5: client receives message, but freeswitch reports 'Error! Message Not Sent'

[Question Answer]

Hi,
   I solved this.  The issue was on the client side.  I needed to confirm
acceptance of the message on the client side and respond to FreeSWITCH:

http://www.sipml5.org/docgen/index.html#acceptMessageFunc

  After doing that FreeSWITCH no longer hangs, and confirms that the
messages was sent successfully in the log.
