Hi everyone,

I have two questions:

In the draft called "Signaled Digits in SIP", the example in section 5 suggests that 
the SUBSCRIBE
is sent using the call leg of the existing INVITE. Does this mean that

SUBSCRIBE CallId == INVITE CallId
SUBSCRIBE To == INVITE To   (the Tag of To excl.)
SUBSCRIBE From + Tag == INVITE From + Tag
SUBSCRIBE Cseq > than previous Cseq for this leg

How should the SUBSCRIBE 'terminate' when a BYE is received for that call leg ?

should
1. the SUBSCRIPTION be left to 'timeout' ?
2. A final notify/subscribe with Expires = 0 be sent ?
3. the SUBSCRIPTION just dies with the call leg.

thanx,
