Summary:                    [patch] No answer to OPTIONS packet because Asterisk
not looking for 's' in default context
Description: 
Hello,

asterisk-1.8.0 installed through yum on CentOS 5.5 32bit. 

My SIP provider is checking if I'm alive with OPTIONS. I must answer to
that request with "SIP/2.0 200 OK". The default behavior is to check if I
have a peer with that IP, then check for "s" in it's context. If not check
for "s" in the guests context (context=XX from general section of
sip.conf). Or I'm missing something?

With 1.8.0 the extension part is missing. Some debug logs:
1.1.1.1 is the SIP provider, 2.2.2.2 is my IP.
