Confirm current details of VQ RTCP-XR sendings

[oliv]

Hello,

As other threads show it, I'm currently digging in VQ RTCP-XR feature.

For my very first tests, I was a bit surprised to capture that when a phone is registered to a SIP B2BUA, it would sent to this B2BUA its VQ RTCP-XR reports: I expected those reports to be directly sent to whatever host I configured.

Let me rephrase this:
My phone is registered to a B2BUA.
A collector is alive and waiting for reports, on the same network but a different address.
At the end of a call, my phone sends to its B2BUA, a PUBLISH message like this
PUBLISH sip:foo@1.2.3.4 SIP/2.0
where:
foo is account.X.vq_rtcpxr.collector_name
1.2.3.4 is account.X.vq_rtcpxr.collector_server_host.

I expected this very same message to be directly sent to Collector (my B2BUA does not support incoming unsollicited PUBLISH messages).

Is it correct behaviour ?
My testing where done with firmware 46.81.0.25.

Best regards
