[SIPForum-discussion] Time interval between requests

[Abhisek Acharya]

Another thing Mustafa.

Let us assume a media session is going on and you send a RE-INVITE to
change the media characteristic.In that case if you cut the call manually
from the sip phone then it should always generate a BYE not a CANCEL.

over to you all the folks in the mailing list.
