If the add the Path header manually, then it is not seen by the registrar/usrloc module, asthe header will only be added when generating the "to be forwarded" message - and this never happens as the message terminates on the registrar. You could try msg_apply_changes() after adding the Path header.

Hi,

Thanks for your reply.

I did try that, but the path is still not stored in location table on
save. I have "use_path" parameter of registrar module enabled.

    Hi,

    you cannot use add_path(), but by creating your own Path header this
    works, e.g.:

    append_hf("Path: <sip:term@HOSTNAME:"+PORT+";lr>\r\n");
    (from our P-CSCF config)

    Then your Proxy should also evaluate the DNS-SRV records.

    Kind regards,

    Hi All,

    Given a situation where there are multiple registrars, behind a
    single load balancer, sharing the same location table in DB, I
    understand that Path can be used to ensure everything works nicely
    with clients behind NAT. So, if UA1 is registered on P1, UA2 on P2,
    and UA1 calls UA2... P1 performs lookup, sees path and sends via P2.

    What about situations where the distribution between registrars is
    being handled client-side through DNS SRV, not a load balancer? Path
    cannot be used then, right? As I understand it, in this instance
    add_path() will do nothing, is this correct?

    Thanks in advance,

    Charles
