Re: [Sipp-users] UDP CHECKSUM ERROR with own UAS scenario






Nevermind, problem solved.
Pebkac, as usual.

Although, the [last_from] directive returns the whole From address from 
the las message, often in format such as "name 
". Is it possible to get just the actual 
address, ie sip:[EMAIL PROTECTED], so that it can be used for Requests, ie 
NOTIFY sip:[EMAIL PROTECTED]:port SIP/2.0?

[Sipp-users] UDP CHECKSUM ERROR with own UAS scenario

2008-07-27 Thread michael 
Hi
I'm running two instances of SIPp to interact with a B2BUA server, and am
getting an odd response from the SIPp server module.
My server sends this SUBSCRIBE (taken from a wireshark trace):

SUBSCRIBE sip:[EMAIL PROTECTED] 
:5071 
SIP/2.0
Call-ID: [EMAIL PROTECTED] 

CSeq: 1 SUBSCRIBE
From: https://crgmail.ee.uct.ac.za/src/compose.php?send_to=mike%40127.0.1.1>:5060>;tag=-608704382
To: https://crgmail.ee.uct.ac.za/src/compose.php?send_to=bill%40127.0.0.1>:5071>
Via: SIP/2.0/UDP
127.0.0.1:5080;handler=SignalServlet;appname=SignalServlet;branch=z9hG4bK8843040021944fcc8abab51066d03b69
Max-Forwards: 70
Content-Type: text/plain
Record-Route:

Contact: "mike" 
Content-Length: 0

to the SIPp server:, which uses the scenario below:






  
  

  

  

  
  
  
  
  
  
  
  

  
  

The response I get back from the SIPp server is a UDP message with title
"UDP CHECKSUM INCORRECT":

Frame 7 (794 bytes on wire, 794 bytes captured)
Ethernet II, Src: 00:00:00_00:00:00 (00:00:00:00:00:00), Dst:
00:00:00_00:00:00 (00:00:00:00:00:00)
Internet Protocol, Src: 127.0.0.1 (127.0.0.1), Dst: 127.0.0.1 (127.0.0.1)
User Datagram Protocol, Src Port: 5071 (5071), Dst Port: 5080 (5080)
Source port: 5071 (5071)
Destination port: 5080 (5080)
Length: 760
Checksum: 0x010c [incorrect, should be 0x9f43 (maybe caused by "UDP
checksum offload"?)]
[Good Checksum: False]
[Bad Checksum: True]
Data (752 bytes)

This causes my server to reply with a 400 Bad Request message, and the
SIPp server does not execute. With wireshark checksum validation turned on
for UDP, all the messages in my scenarios get flagged for checksum errors,
but the logical entities carry on executing perfectly, until such time as
the SIPp server is messaged.
Any ideas as to my problem?
Thanks, mike
