Hello,
i'm encountering a matter while receiving an INVITE from a third-party proxy module to the Kamailio s-cscf module (version: kamailio 4.1.0 (x86_64/linux) 350d2e)
Accordling to the RFC3325 section 9.1 The P-Asserted-Identity Header,
The P-Asserted-Identity header field is used among trusted SIP entities (typically intermediaries) to carry the identity of the user sending a SIP message as it was verified by authentication. PAssertedID = "P-Asserted-Identity" HCOLON PAssertedID-value *(COMMA PAssertedID-value) PAssertedID-value = name-addr / addr-spec A P-Asserted-Identity header field value MUST consist of exactly one name-addr or addr-spec.
In our scenario the received INVITE contains a P-Asserted-Identity header with an addr-spec value format, so without angle brackets, as described in RFC2822
In Kamailio log I see that it rejects this header asserting it is malformed.

Fix the client!
Can you confirm this issue?
Hello,
Can you paste here the full header as it is received? It will help to see if something is wrong with it or with the code.
Cheers, Daniel
