[SR-Users] handle_ruri_alias() and multiple aliases

[Denys Pozniak]

Hello!

I need help understanding how the *handle_ruri_alias()* function works.
*Call-flow:* Upstream operator -> Kamailio Proxy -> Edpoint.

The upstream operator in the initial SIP INVITE in the Contact field sends
us an alias parameter, in turn, our Kamailio Proxy adds its own too.
The Contact after the Proxy looks something like this:

*Contact:
<sip:10.0.0.115:5060;alias=10.0.0.115~5060~1;alias=3.3.3.3~5060~1>*

When the Endpoint sends us a SIP BYE, then the *handle_ruri_alias()*
absorbs not the last alias, but the first one, and this leads to the
incorrect formation of a $du.
The RURI after the Proxy looks something like this:

*Request-Line: BYE sip:10.0.0.115:5060;alias=3.3.3.3~5060~1 SIP/2.0*

The first thing that comes to mind is a modification of the original
Contact field with storing it's within a dialogue ...

Is it possible to elegantly solve this problem?
