This issue happens a lot less frequently on the ios-ngn-stack build r180 that I 
am using at the moment, although still occurs. This issue is causing a serious 
issue for us to launch our product.

For now we cannot do anything as we cannot reproduce the issue using iDoubs.
If you have log trace, please attach.

It's difficult to reprocude. Here's another example of this.

Did you reproduced the issue with iDoubs or your app?

This is with my app with ios-ngn-stack.

This doesn't happen every time, its reproduced ~1/10 calls.

Probably an issue with your code because using iDoubs it's not possible to 
reproduce.
It should be easy to fix the issue as you already have the line producing the 
issue and the errno.
I don't see how we can help fixing an issue in your code.

The lines listed are ios-ngn-stack lines ie/ lines in the doubango/idoubs 
stack. It seems to happen when the sip stack seems to stop.

I've compared my codebase to idoubs and even refactored things to be identical 
and i'm getting the same issues.

Requesting this to be marked as Invalid, It looks like this was to do with my 
sip server. I've tweaked the SIP authentication and it appears fixed.
