[SR-Users] Kamailio 4.1.0 P-Asserted-Identity value

[Flavio Battimo]

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.

Can you confirm this issue?
