> Attached patch fixes the following issues in chan_sip:
> 1) Use astobj2 as a true hash table instead of doing a 'fancy' linear searchg over the entire list trying to find the correct entry.
> 2) Fix tag matching. Currently in pedantic mode it is impossible to handle a call that is being forwarded by a proxy, eg receiving a 183 (client, no answer) and a 200 (voicemail) from 2 different UA's.
> 3) Fix spiralling calls. Each new branch creates a new pvt.
> 4) Part of 2) is to not clear the SIP_PAGE2_DIALOG_ESTABLISHED flag on a BYE, to be able to absorb retransmissions.
> I'm sorry this is all in one patch, but I'm a little time contraint to split them now.
