[asterisk-ss7] Need some information on SS7 parameters

[research at businesstz.com]

Hello List

I am setting up a small demo site using SS7 and one of the requirement is
to be able to unhide the numbers and locate exact location of the caller
(BTS ID). Vodafone uses Nokia-Siemens switch and has confirmed that the
parameters will be sent to the us.

I just want to know how do read those information from the dialplan to be
able to present them to the Agent

Thanks
Samwel Muro
