Hi Klaus and Raul,
Thanks for your answers ... I think I'm more clear now.
ciao, flo
See Raul's email for the standardized headers.
These are often used for
provider interconnect and also supported by recent PSTN gateways.
IIRC there is no explicit support for PAI, PPI in Asterisk, so you would have to
use the SIP_HEADER function and manually parse the headers.
So, as long as you use it only internally, you can use the obsolete RPID header
too, actually you could any header.
