[SIPForum-discussion] Sip message for Switched off Mobile Phones

[Dilip Kumar]

Hi Anthony,

In most cases from the mobile network, when there is annoucements related to
the subscriber the cause code which comes after it is "normal unspceified"
which is isdn cause code 31..As per RFC 3398 it is mapped with 480
temporarily unavailable.

With Regards,
D. Dilip Kumar
