Given that the asterisk guys often don't seem to care too much for SER I think I will probably have better luck getting this question addressed here.

I have seen this referred to as using asterisk like a b2bua in conversations on this list and in other documentation. -- Tracy Reed http://copilotcom.com This message is cryptographically signed for your protection.
