[Asterisk-Users] RDNIS

[Steve Underwood]

Hi,

You have it about right. It may really not be available on the 5ESS you 
connect to, though. I think its an optional feature on many switches. 
The text yuo quote makes it sound like a cost option on this one.

What goes in the RDNIS field is rather variable. On a Hua Wei switch I 
could choose from a fairly long list of things. For them it seems to be 
a place to stuff any extra info you want :-)

If you are mere customer of the mighty powerful telco, and they say you 
can't have an RDNIS field, then I guess you can't have it. The only 
times I have seen the field populated is when working fairly closely 
with the operator of the switch, and it was custom configured for me.

Regards,
Steve
