thanks,
i will use the RFC 3325 but i don't know a soft phone supported this RFC.
You should read that RFC since it doesn't involve final phones but proxies and
gateways.
please if you know one give me its name ou a link to
download it.
The tipicall scenario is:
- A phone sends an INVITE. The "From" is "bob".
- The proxy authenticates the INVITE.
- Before forwarding the INVITE to the PSTN gateway, the proxy adds a
P-Asserted-Identity header containing the asserted identity, that could be a
PSTN number as callerID or any other username, examples:
- P-Asserted-Identity: <sip:+12345678@domain.org>
- P-Asserted-Identity: <tel:+12345678>
- P-Asserted-Identity: <sip:bob.home@domain.org>
- When any other node in the network that trusts this proxy receives this
INVITE from it, it trusts the PAI header and uses it as a callerid.
