Hi All,
 
By setting the audio port to zero in reinvite , will it invoke hold?
 
call folw:
 
A                       B
  ----INV------->
 m=audio 29590..
 < ------200------------
m=audio 4100..
--------ACK----------->
   call established 
 
---------INV-(hold)---->
c=IN IP4 0.0.0.0
m=audio 29590..
a=sendonly
<----------200------------
m=audio 4100..
----------ACK---------->
 
---------INV--(hold)----->
c=IN IP4 0.0.0.0
m=audio 0...
a=inactive
