[Sipp-users] Looping capability in SIPp

[Newsgroup U. <gr...@gm...>]

Hey All,

I am new to SIPp and am trying to use it to simulate actual SIP devices. For
example:

   1. Register
   2. Subscribe to various devices in the contact list (approximately 50
   for load testing)
   3. Receive Notify for all these subscribes
   4. UnRegister

I guess I can completely hard code this scenario and get it to work.
However, I would like to find out if any of the following features are
available, which would make it much easier for me to implement this
scenario:

   1. Is there a way I can loop the subscribe messages so that I can send
   each subscribe message with some new fields, for example the "from" ID, the
   "Event" header, etc? If there was a way in which I can set a variable with
   custom data, I think I can achieve this with the help of labels and the
   "next" attribute of the send message. However, I have not been able to find
   a way to set variables outside of the regex scenario, which can also set it
   only if the regex matches.
   2. Another neat feature would be the ability to group a sequence of
   messages and refer to this sequence. for example, after every subscribe, one
   can expect 200, 408, 403, 407, etc responses. If I need to send 2 subscribes
   right now, each one of them is followed by these optional responses, making
   the XML file quite huge. If I could have grouped these messages in one
   section, I could just refer to that group after every subscribe. Of course,
   something even better would be to have this feature as well as the one in
   item 1 above, which would completely eliminate the need to create 2 send
   sections for 2 subscribe messages.
   3. My ultimate goal is to be able to continuously send Subscribe
   messages and then handle notify messages as and when they are received. I do
   not see a good way of doing this either. For example, if I am sending 10
   subscribes, one after the other (and also handling their respective
   responses), I might get a notify in between one of these steps. How do i
   handle this without also adding an optional recv message for "Notify"?

I hope I have been able to clearly explain the scenarios I'm trying to
simuate. Thank you in advance for your help.

Thanks,
