[Sipp-users] sending 183 with SDP

[Makarand Bhagwat]

Hi all,

I am trying to simulate a gateway and tryiing to send a 183 Session Progress
with SDP.
However everytime I insert 183 with SDP sipp doesnt send 183 message...when
I remove the SDP from 183 it sends it.

Any ideas what could be going wrong. ?

Thanks,
Makarand

Can you send your XML scenario?

Hi,

Is there a way by which I can change the number of retransmits in Sipp. At
present I know its something like 7, I would like to change it to some
higher number.


Thanks in advance,

Makarand

Hi,

this has been added in the latest snapshot:

2005-08-24 07:43 ojacques

* call.cpp, call.hpp, sipp.cpp, sipp.hpp: New -max_retrans command
line parameter to max out UDP retransmissions. This allows to use
SIPp to monitor SIP application/servers and detect issues early


Is it what you were looking for?

Hi Makarand,

- Download the latest snapshot:
http://sipp.sourceforge.net/snapshots/sipp.cumulus.2005-08-24.tar.gz
- use -max_retrans option to indicate the maximum number of retransmissions
(UDP only).
max_retrans is using the maximum between UDP_MAX_RETRANS_INVITE_TRANSACTION
or UDP_MAX_RETRANS_NON_INVITE_TRANSACTION and the value of max_retrans
option. So this will not be enough to have "infinite" re-transmission.
You will need to change in call.hpp UDP_MAX_RETRANS_INVITE_TRANSACTION and
UDP_MAX_RETRANS_NON_INVITE_TRANSACTION and re-compile for that.

I didnt quite follow what you said in your email.
I am running a client and server script where the client acts as the
phone, and the server acts as a registrar.
the scenario is as follows.
register ------------------------------>
401 <---------------------------------
register with credentials ----------------------->
200 OK <--------------------------------
the second part keeps repeating to simulate the keep alives.
At present what we observed is that, during high cps/rps if the register
message is lost; including the retransmits. Thus we cannot simulate
conditions where we maintain a fixed number of registrations on the proxy.
Hence what I want to do is to change the retransmits to infinite / high
number...so that I dont have to worry about the lost register messages.
Thanks,
Makarand
