 Indeed not, and that's what I was trying to say in my response yesterday.

Oh yes, I noted it there as well and then saw it also in the document I referenced. Thank you for the information. 

 First, don't confuse the OpenSIPS and Kamailio SST modules, even though they do appear to be identical. Still, two different projects.

My apologizes, my google search grabbed me the wrong project. The real one is here, incase any one is referencing this thread: http://www.kamailio.org/docs/modules/3.1.x/modules_k/sst.html

Second, if you read this documentation, you'll find that nowhere in there exists the capability for Kamailio to initiate SST reinvites itself. All this module provides is policing for the SE value and the ability to peg dialog state to it by making Kamailio SST-aware--that is, aware of SST-motivated reinvites that still very much have to be initiated by the endpoints themselves.

I see what you mean. 

Perhaps what I could do with the module is set a long minimum timeout, long enough that it would allow our calls to complete before the re-invite occurs. A messy solution but  might work in a pinch.

In short, there's nothing you can do here except fix the endpoints.

Ok thank you for the advice. We will start testing what softphones we can find that support the functionality.

I hope all is going well with you.

All the best.

Will
