"Mapped to" parameter in the registration-cache
Hello,
I came across an SBC with a configuration style unusual to me. For instance, in the registration cache there is a parameter "Mapped to" under the SD info section which I have never seen before:
SD Info:
Contact: sip:100128118002@172.18.1.10:16094
Mapped to: 172.18.1.10:16094
Call-ID: f632adbdf7ca42d39b03b2ca1c6ea2a4
Usually SD info looks like following, i.e there is "Realm" instead of "Mapped to" (at least in my usual canonical deployments)
SD Info
:
Contact: sip:926-v3j3q65ar3on0@3.3.2.4:5061
Realm: public-sip-access
Call-ID: 421bd53bd97c4ebe838484bf20065c5d
Does anybody know where this "Mapped to" came from? What can be a reason of this mapping?
