Hi,
 
Iam Pretty new to this SIP ,I have small query on SIPp script. 
 
My Voipohne is failing when it recieves a SIP INIVTE with P-asserted Identity.I 
have done some modifications to my code. 
 
 Generally  P-asserted Identity is provided by providers.
To simulate this issue I wrote a Sipp script adding  P-asserted feature in SIP 
INVITE .I have tested  with IP call .it works. Is this a correct way of 
simulation or do i need to test using Proxy servers.
  
Please see the Sipp script of SIP INVITE.
