SIP2Megaco Busy

Hi,,

I'm new to this mailing list. Right now, i'm studying about interworking
between megaco and sip.
I simulated a call from SIP phone to Analog phone which was busy. Here i
attach the captured data using ethereal, you can view the callflow by
writing "*(megaco and ip.addr==10.14.32.186) or (sip and
ip.addr==10.14.32.185) or rtp*" in filter textbox.

I have a few questions about that captured data :
1. Why did MGC create a context and the terminations for the analog phone
and etc (captured data No. 2079 - ~)? Isn't it busy?
2. if it was so, why did in no 2114, the MGC send modify (cg/dt) to MG?
3. Why did the MGC create 2 context? first, when the sip phone send the
INVITE; second, when the analog phone onhook,,,


I hope my questions are all clear to be understood,,,because i'm not too
good in english.
Hopefully, you guys can help me.

Regards,

Jati
