Have an issue with BYE routing in a lab setup, any suggestions on what I should be looking
at?
Topology:
UA1 <-> NAT device 1 <-> Proxy1 <-> Registrar/B2BUA <-> Proxy1
<-> NAT device 1 <-> UA2
All UA to UA calls flow through B2BUA.
All IP’s are public except for UA1 and UA2.
-Both endpoints can call each other.
-If the caller hangs up first, BYE is routed properly.
-If the callee hangs up first, BYE causes proxy to send 478.
On calls where BYE results in 478:
if(!isdsturiset()) {
……….…………………….not executed
handle_ruri_alias()
}
return;
Example issue call: UA2 to UA1, UA1 hang-up.

I’ve tested with two different UA types and same thing happens, must be a result of the
B2BUA sending the alias in the To header of the invite.

I don't know mate, something wrong with your config, all I can say from the
provided info is that there's no place for *alias *in From/To headers. They
must be in Contact/RURI.

Something wrong with the above From, no closing ">", also there's no
place
for *alias *in From headers.

Have an issue with BYE routing in a lab setup, any suggestions on what I
should be looking at?
Topology:
UA1 <-> NAT device 1 <-> Proxy1 <-> Registrar/B2BUA <-> Proxy1
<-> NAT
device 1 <-> UA2
All UA to UA calls flow through B2BUA.
All IP’s are public except for UA1 and UA2.
-Both endpoints can call each other.
-If the caller hangs up first, BYE is routed properly.
-If the callee hangs up first, BYE causes proxy to send 478.
On calls where BYE results in 478:
if(!isdsturiset()) {
……….…………………….not executed
handle_ruri_alias()
}
return;
Example issue call: UA2 to UA1, UA1 hang-up.

Indeed. The From/To headers are cosmetic in this regard; no attribute of
them would cause a routing problem[1].

[1] Well, except for missing tags, I suppose; but even then, this would
not pose a routing problem, just a dialog party identification problem
to one or more UAs.

Hello,
What about a syntax error in those headers?
I am curious about this :
"sip:398@ B2BUA_IP:"
Why a space after "@"?
Best regards,
Luis

That could jam the SIP parser and cause the message to be dropped, definitely.

The space is just a result of me sanitizing the example.
The issue here is most certainly the way the B2BUA is handling the contact alias sent by
kamailio. I will have to come up with another plan.
Thanks for the input!
