I think the answer is "no".
RFC3261 mandates UAC only insert a Via header when sending request.
Sec 8
When the UAC creates a request, it MUST insert a Via into that request.
And respnse with multiple Via would be rejected by UAC.
Sec 8.1.3.3
If more than one Via header field value is present in a response, the
UAC SHOULD discard the message.
The presence of additional Via header field values that precede
the originator of the request suggests that the message was
misrouted or possibly corrupted.

Subject: [Sip-implementors] Can multiple Via header be present in
initialINVITE request ?
Hi,
Can multiple Via header be present in initial INVITE request ?
I mean to say when first time INVITE request is generated from UAC
without traversing any PROXY can contain multiple Via header ?
If yes then what is the need of having multiple Via header in initial
INVITE request?
Thanks
Sourav
