[asterisk-users] Determine if Call is from a cellular phone

[Ron McLeod]

Depending on how you connect to the PSTN and what type of call is being
made, you may have access to the ANI "II" digits.  The "II" digits tell you
what type user/service originated the call from such as: regular phone,
hotel/motel guest phone, pay phone, inmate phone, and various types of
cellular/PCS phones.

See
    http://www.nanpa.com/number_resource_info/ani_ii_assignments.html

for the digits values and what they mean.

With LNP in the US, there really is no way to determine if the call 
originates from a landline, a VOIP line or a wireless line
Most numbers are portable and even the NPA doesn't tell much any more.
I have a wireless phone with a ( former ) landline number, and a VOIP 
line with a ( former ) wireless number.

I have to wonder why you care.
