[OpenSIPS-Users] Opensip as transaprent inbound proxy for asterisk

[Bakko]

Hello,

I'm use this procedure to know original IP (long way):

first define a context on opensips trunk configurated on Asterisk., then 
I use this dialplan block:

[opensip]
exten => _X.,1,Set(uri=${CHANNEL(uri)})
same => n,Set(uri2=${CHANNEL(from)})
same => n,Set(uri=${CUT(uri,@,2)})
same => n,Set(uri=${CUT(uri,:,1)})
same => n,Gotoif($["${uri}" = ""]?fromuri)
same => n,Gotoif($[${DB_EXISTS(ip/${uri})} = 0]?block)
same => n,Goto(${DB(ip/${uri})},${EXTEN},1)
same => n,Hangup
same => n(fromuri),Set(uri=${CUT(uri2,@,2)})
same => n,Set(uri=${CUT(uri,:,1)})
same => n,Gotoif($[${DB_EXISTS(ip/${uri})} = 0]?block)
same => n,Goto(${DB(ip/${uri})},${EXTEN},1)
same => n,Hangup
same => n(block),NoOP(bloqueo de IP)
same => n,Hangup

IF the IP is not present on contact header is present on from header. 
Then I created family key on internal Asterisk database with this sintax:

IP 1.2.3.4 name

Asterisk check if The IP is present on database and if true send the 
call to context "name".

 From there you can use the dialplan you want.

Regards.
