At SIP protocol, UAC and UAS roles are logical only and its role is
relevant during current transaction (e.g request-response).
UAC is an entity sending the request and UAS is one responsing request
received. For example: in terms of real telephony, both callee and
caller are able to hang up the call (that is BYE request sent).
Since SIPp behaves according to XML scenarion you're have enough
flexibility to send requests and response from each side. See example
attached...

Subject: Re: [Sipp-users] not able to send BYE from UAS
Hi,
I have never got this straight in my head regarding SIPp UAC and UAS
instances.
* Can one send SIP requests from SIPp running in UAS mode (e.g.
BYE, INVITE, PRACK etc)?
* Can one receive SIPp requests to SIPp running in UAC mode ?
* If so, why are there UAC and UAS SIPp modes anyway?
Any comments would be greatly appreciated.

Subject: [Sipp-users] not able to send BYE from UAS
Hi all,
We are able to send a BYE request from the UAC (sender) side. But if
we are trying to send a BYE request from the UAS (receiver) side we are
receiving 400 Bad request.
This is the BYE message we are sending from the UAS side to the UAC
side.
<!-- BYE message from UAS-->
