Outbound-15 4.2.1 says:

power, for example). If the set has more than one URI, the UAC MUST
send a REGISTER request to at least two of the default outbound
proxies from the set.
i thought that i lost this battle, but it is a nice surprise that the
text has been changed and with two proxies in the set, ua MUST
register
with both.
That's why I kept saying we had fixed that part of outbound per your
request.
now if the ua has two network interfaces (3g and wlan, for example)
and
the user want to use both of them simultaneously, is it so that
inbound call
gets forked?
My understanding was that there is a contact prioritization. The proxy
uses the first contact as long as the flow associated with that
contact has keepalive. If that flow fails, then the proxy falls over
to the second contact and flow.
and further, is there any text anywhere forcing the ua to register
both
of its contacts with both proxies?
Only in 3GPP specs, I believe.
