[Users] Route, Record Route and quintum

[Bogdan-Andrei Iancu]

Hi Iqbal,

considering 200 OK the Route Set:
    RR: <sip:212.156.5.135;ftag=c3ac7b24-a;lr=on>
    RR: <sip:111.222.333.444;ftag=c3ac7b24-a;lr=on>
    CT: <sip:0044123456789 at 212.156.5.134:5060>

the ACK should be:
a)if loose router:
    RURI: <sip:0044123456789 at 212.156.5.134:5060>
    R: <sip:212.156.5.135;ftag=c3ac7b24-a;lr=on>
    R: <sip:111.222.333.444;ftag=c3ac7b24-a;lr=on>
b) if strict router:
    RURI: <sip:212.156.5.135;ftag=c3ac7b24-a;lr=on>
    R: <sip:111.222.333.444;ftag=c3ac7b24-a;lr=on>
    R: <sip:0044123456789 at 212.156.5.134:5060>

the ACK you posted looks like an unsuccessful attempt of a strict routing.

regards,
bogdan
