REDIRECT_TYPE [MCS | RFC3261] This parameter is a command used to select different
protocols for IP Deskphone redirection. The default
setting is MCS.
- MCS – when the IP Deskphone receives either 301
(moved permanently) or 302 (moved temporarily)
during registration, it is assumed the IP Deskphone
is moved to a new system (proxy+registrar) and all
subsequent messages are sent to the new
address.
- RFC3261 – the IP Deskphone assumes that, if
during registration, a 301 (moved permanently) is
received, the message contains a new registrar
address. The IP Deskphone tries to register to the
registrar using the existing proxy.
