Hi:
Yes, but you should care about request overlap. Maybe this
can be helpful.

This question keeps coming up in various forms.  See a
thread 

https://lists.cs.columbia.edu/piperm
ail/sip-implementors/2006-November/01487
7.html



Section 14.1 clearly explains that for ReINVITEs.

   Note that a UAC MUST NOT initiate a new INVITE
transaction within a
   dialog while another INVITE transaction is in progress in
either
   direction.

Requests like OPTIONS and BYE are regular transaction, and I
don't see any
text in RFC prohibiting sending out another regular
transaction, while one
is pending.

In same Section 14.1

   However, a UA MAY initiate a regular transaction while an
INVITE
   transaction is in progress.  A UA MAY also initiate an
INVITE
   transaction while a regular transaction is in progress.

My understanding is regular transactions can be sent out
while one is
pending.
