re-invite problems?

Description
Hello,
Why does the audio stop playing when I call wbdemo@conf.zipdx.com and press 2? The purpose of pressing 2 is for a re-invite.
Full sip_trace.log attached for the session of the call and the sip2sip logs.
I see this in the sip2sip logs:

The codec line is changed from opus/48000/2 to juust opus/48000. This is detected by us as a codec change mid-call, which we don't support.
While we should support this, because it's essentially the same codec, I'm afraid it's complicated. You might have better luck asking ZipDX as well.

Hello,
Thanks for the update. Disabling the opus codec all together will result in a
successful re-invite.
I had to specifically disable opus from the sip2sip app instead of rearranging
the priority, otherwise it continued to connect over opus. Is that expected?
Thanks,
sean

That's up to the recipient actually. Basically your SDP says "key, I support these codecs" and the recipient will say "cool, I choose that one".

This issue may be closed. I've been able to call the VUC from sip2sip for two consecutive weeks, after disabling opus.
Special thanks to Michael Graves and Saúl Ibarra Corretgé.
