Accordingly to this capture, there was still user=phone parameter in the
outbound INVITE requests. Double check that you have used the full SIP URI
without this parameter, and you're uploading the right capture file.

Overall, it's notable that the proxy uses a different URI to send requests to
the client (see NOTIFY in packet 6) compared to what is reported in the
registration responses: there we have a contact URI as pertains to the local
private network. This is another indication that there may be an ALG between
the client and the proxy that is rewriting addresses and URIs in SIP messages.
This is where the breakage most likely occurs.
