Hi all, I have the following setup: -sip device is registering to OpenSIPS setup as a mid_registrar who then fowards registers to asterisk once they are authenticated -OpenSIPS is setup in contact throttling mode with outgoing expires set to 3600 sec.
The scenario I came accross is the following: "Registration - OpenSips mid_registrar" ┌─┐ ║"│ └┬┘ ┌┼┐ │ ┌────────┐ ┌────────┐ ┌┴┐ │OpenSips│ │Asterisk│ Alice └────────┘ └────────┘ │REGISTER (expires 3600 sec)│ │ │───────────────────────────> │ │ │ │ │ 401 Unauthorized │ │ │<─────────────────────────── │ │ │ │ │REGISTER (expires 3600 sec)│ │ │───────────────────────────> │ │ │ │ │ │ REGISTER (expires 3600 sec)│ │ │ ───────────────────────────> │ │ │ │ │ 200 OK (expires 120 sec) │ │ │ <─────────────────────────── │ │ │ │ 200 OK (expires 3600 sec) │ │ │<─────────────────────────── │ │ │ │ │ │ │ │ │ │ │ │ │ Alice ┌────────┐ ┌────────┐ ┌─┐ │OpenSips│ │Asterisk│ ║"│ └────────┘ └────────┘ └┬┘ ┌┼┐ │ ┌┴┐ 1-the sip device sends a REGISTER to OpenSIPS (expires 3600) 2-OpenSIPS authentifies the REGISTER and sends back challenge to the sip device 3-sip devices sends authenticated REGISTER to OpenSIPS, here the expires would normally be changed to 3600 but in this case it was already set at 3600. 4-Asterisk receives the REGISTER, alters the expires to 120secs and replies 200 ok to OpenSIPS 5-OpenSIPS forwards the 200 ok but with 3600 sec expires. My Questions is: I was expecting OpenSIPS to automatically update the expires in it's usrloc to 120 seconds and send 120 sec in its 200 ok. Should I be doing something in a return route for the REGISTERs in order to update that and send the correct value or should opensips be doing that automatically? Currently I am calling mid_registrar_save("location") when I receive the REGISTER but doing nothing when I receive the 200 ok. Thanks in advance Dominic
