Hello, Two times in the past week I have had some issues with the bindings of the sip mapping expiring: Binding 'user','sip:user@x.x.x.x:5060' has expired Does anyone know what this is and why it happens? I appreciate any input you may have. Thanks, Hekate _________________________________________________________________ All the action. All the drama.
