[OpenSIPS-Users] Mid-Registrar Absorb 2nd Register(w/ AuthHeader) Request - Only on Reg Renewal.

[Ali Raza]

Hello Guys, 

I am new to OpenSIPS. I am currently test mid-registrar module with FreeSwitch and I am facing a issue not sure if its a bug or its me. 

Let me explain whats happening: 

I am running OpenSIPS mid-registrar in contact-throttling mode(mode:1) with usrloc mode:0 - because mid-registrar was crashing again and again then I saw the post https://github.com/OpenSIPS/opensips/issues/1094 - so that issue is now gone with usrloc mode:0. 

When I run opensips my devices(soft phone: zopier and sip phone: fanvil) register perfectly but as soon the registration time for fanvilphone is reaching expiry(outging expiry) opensips passes my registrartion request to freeswitch - Freeswitch sends back 401unauthorised message which is delivered to the phone by opensips. This time phone sends register request with AuthHeader but this request gets absorbed by mid-registrar and reply from UAC with AuthHeader never reach UAS and freeswitch then remove the registrartion from its database assuming the UAC is dead. But when the softphone-Zopier outgoing register expiring somehow Softphone sends the register request with AuthHeader and as OpenSIPs forwards 1 register request to freeswtich - Freeswitch renew its registrartion. So softphone remain registered and works fine. 

2nd/Renew Registration from FanvilPhone: 

1. UAC==Reg==>OpenSIPS==>FreeSwitch 

2. FreeSwitch==401==>OpenSIPs==401==>UAC 

3. UAC==Reg w/Auth-Header==>OpenSIPs(Absorbe by mid-registrar: Returncode: 2) 

4. OpenSIPs==Reply 200==>UAC (so actually phone thinks its registered) 

2nd/Renew Registration from SoftPhone Zopier: 

1. SoftPhone==Reg w/Auth-Header==>OpenSIPs== Reg w/Auth-Header==>FreeSwitch 

2. FreeSwitch==Reply 200==>OpenSIPs==Reply 200==>SoftPhone-Zopier. 


MY OPENSIPS CONFIG -- USED FOR MID-REGISTRAR: 

#### USeR LOCation module 
loadmodule "usrloc.so" 
modparam("usrloc", "nat_bflag", "NAT") 
modparam("usrloc", "db_mode", 0) 
modparam("usrloc", "use_domain", 1) 

#### MID-REGISTRAR module 
loadmodule "mid_registrar.so" 
modparam("mid_registrar", "mode", 1) /* 0 = mirror / 1 = ct / 2 = AoR */ 
modparam("mid_registrar", "outgoing_expires", 180) ##Set to low for testing purpose. 
modparam("mid_registrar", "insertion_mode", 0) /* 0 = contact; 1 = path */ 

if ( !(is_method("REGISTER")) ) { 
if (check_source_address("10")) { 
xlog("looking up $ru!\n"); 
if (!mid_registrar_lookup("location")) { 
t_reply("404", "Not Found"); 
exit; 
} 

t_relay(); 
exit; 
} 
} 

if (is_method("REGISTER")) 
{ 
#mid_registrar_save("location"); 
xlog("BEFORE IT PASS TO MID-REG SAVE!"); 
mid_registrar_save("","m"); 
switch ($retcode) { 
case 1: 
xlog("forwarding REGISTER to main registrar ($$ci=$ci) - $fd\n"); 
#Call script to set $ru - Testing! 
#perl_exec("dest_host","$fd"); 
$ru = "sip:dispatcher\@10.10.7.206:5070"; 
xlog("NEW HOST VALUE: $ru"); 
t_relay(); 
break; 
case 2: 
xlog("absorbing REGISTER! ($$ci=$ci)\n"); 
break; 
default: 
xlog("failed to save registration! ($$ci=$ci)\n"); 
} 
exit; 
} 


LET ME KNOW IF YOU NEED ANYTHING ELSE. 

THANKS!
