#### Description <!-- Describe your changes in detail --> - Contacts are now added at the end of the list. - hfl(Contact)[index] is now returning in the correct order.
Currently, if a sip message contains multiple Contacts or just 2, let's say ``` Contact: <sip:bob0@example.com>;expires=3600,<sip:bob1@example.com>;expires=3600,<sip:bob2@example.com>;expires=3600 Contact: <sip:bob3@example.com>;expires=3600,<sip:bob4@example.com>;expires=3600,<sip:bob5@example.com>;expires=3600 ```
contacts are stored in the reversed order, ie bob2, bob1,bob0 and bob5,bob4,bob3.
This can be seen with a simple config file such as: ``` #kamailio.cfg ... request_route { ... xlog("L_INFO", "Contact headers: $hfl(Contact)\n"); xlog("L_INFO", "Contact headers 0: $(hfl(Contact)[0])\n"); xlog("L_INFO", "Contact headers 1: $(hfl(Contact)[1])\n"); xlog("L_INFO", "Contact headers 2: $(hfl(Contact)[2])\n"); xlog("L_INFO", "Contact headers 3: $(hfl(Contact)[3])\n"); xlog("L_INFO", "Contact headers 4: $(hfl(Contact)[4])\n"); xlog("L_INFO", "Contact headers 5: $(hfl(Contact)[5])\n"); xlog("L_INFO", "Contact headers 6: $(hfl(Contact)[6])\n"); xlog("L_INFO", "Contact headers 7: $(hfl(Contact)[7])\n"); xlog("L_INFO", "Contact headers -1: $(hfl(Contact)[-1])\n"); xlog("L_INFO", "Contact headers -2: $(hfl(Contact)[-2])\n"); xlog("L_INFO", "Contact headers -3: $(hfl(Contact)[-3])\n"); xlog("L_INFO", "Contact headers -4: $(hfl(Contact)[-4])\n"); xlog("L_INFO", "Contact headers -5: $(hfl(Contact)[-5])\n"); xlog("L_INFO", "Contact headers -6: $(hfl(Contact)[-6])\n"); ```
that prints in the log all the contacts reversed:
``` Contact headers: <sip:bob2@example.com>;expires=3600 Contact headers 0: <sip:bob2@example.com>;expires=3600 Contact headers 1: <sip:bob1@example.com>;expires=3600 Contact headers 2: <sip:bob0@example.com>;expires=3600 Contact headers 3: <sip:bob5@example.com>;expires=3600 Contact headers 4: <sip:bob4@example.com>;expires=3600 Contact headers 5: <sip:bob3@example.com>;expires=3600 Contact headers 6: <null> Contact headers 7: <null> Contact headers -1: <sip:bob3@example.com>;expires=3600 Contact headers -2: <sip:bob4@example.com>;expires=3600 Contact headers -3: <sip:bob5@example.com>;expires=3600 Contact headers -4: <sip:bob0@example.com>;expires=3600 Contact headers -5: <sip:bob1@example.com>;expires=3600 Contact headers -6: <sip:bob2@example.com>;expires=3600 ```
This PR fixes and produces: ``` Contact headers: <sip:bob0@example.com>;expires=3600 Contact headers 0: <sip:bob0@example.com>;expires=3600 Contact headers 1: <sip:bob1@example.com>;expires=3600 Contact headers 2: <sip:bob2@example.com>;expires=3600 Contact headers 3: <sip:bob3@example.com>;expires=3600 Contact headers 4: <sip:bob4@example.com>;expires=3600 Contact headers 5: <sip:bob5@example.com>;expires=3600 Contact headers 6: <null> Contact headers 7: <null> Contact headers -1: <null> Contact headers -2: <sip:bob5@example.com>;expires=3600 Contact headers -3: <sip:bob4@example.com>;expires=3600 Contact headers -4: <sip:bob3@example.com>;expires=3600 Contact headers -5: <sip:bob2@example.com>;expires=3600 Contact headers -6: <sip:bob1@example.com>;expires=3600 ```
The `contact headers -1: <null>` if fixed via #3697.
