Summary:                    [patch] RFC 3372 SIP-T receive implementation
Description: 
The patch enables you to receive sip-t packets and decodes some fields.

The sip-t means that in the initial invite the content is multipart with
1) the sdp part
2) application/isup part
this second part contains the IAM message from the SS7. This is cool
because it contains some fields that are not available in the basic sip
packet like:
Origination line:
0- Plain Old Telephone Service (POTS) - non-coin service requiring no
special treatment
70- Code 70 identifies a line connected to a pay station (including both
coin and coinless stations) which does not use network provided coin
control signaling.  II 70 is used to identify this type pay station line
irrespective of whether the pay station is provided by a LEC or a non-LEC. 
II 70 is transmitted from the originating end office on all calls made from
these lines.

For some carriers this is the method to send the payphone information. If
you use toll free numbers this is a cool feature to have, so that you can
bill the payphone too.

Let me know how it worked for you. (For me it's working well).

Cheers
