Info Digit AS5400

Hello,

Our current setup is basically Cisco AS5400 -> Lucent Excel Switch

We are trying to setup a new VoIP connection to receive calls with info digits so that we know if a person is calling from a payphone or not.

The call itself goes through to our switch and connects, but the info digit is not being forwarded.

The new vendor gives two options on where the info digit will be placed.

In the invite message or the from message.


INVITE sip:12345678901234@xxx.xxx.xxx.xxx;isup-oli=00 SIP/2.0

From: "1234567890" <sip:1234567890@xxx.xxx.xxx.xxx;isup-oli=00>;tag=9jZvvUFj41e7o

As you can see, they are sending the line "isup-oli=00"

When I debug ISDN, I'm not seeing anything that seems remotely close to an info digit.

I've search online and found words like codeset, Locking shift, but none of those shows up on the debug.

ISDN GTD is enabled on the serial interface.
