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.
