[Asterisk-Dev] delayed sip answer

[lconroy]

Hi Folks,
... or, to phrase it another way, the "SIP FXO" is badly broken, and  
no one is likely to want to change any code that would break the  
existing chan_SIP for everyone else, which you already surmise is  
what would be required to accommodate the broken unit.

Of course, if you wanted to do such an abomination in your  
installation, then chan_sip.c awaits. Rely on early media? - Gak!

Trust me on this, just say no - I would be surprised if the -users  
list gave any better answer.
