How is DNIS information sent to an LNS from a remote access server (e.g. 5300) over an L2TP tunnel?

[admin_2]

I want to tunnel dialup sessions from a RAS (e.g. 5300) to an LNS device. From the LNS, I want to select AAAA servers based on DNIS information. Question - how is the DNIS information sent from the LAC to the LNS? Which L2TP AVPs are used?

Have a look at AVP 21 (Called Number) and AVP 22 (calling number).
