Aastra Telecom REV 06 Issue Number Description of Fix DEF08852, DEF07873, DEF08132, DEF08245

	5i Series IP Phone Release Notes
	Issues Resolved on Series 5i Phones in Release 2.2
Issue Number	Description of Fix
DEF08852	Auto-answer calls are no longer rejected when you are already in a call; they are
	now treated as normal calls. The previous behavior affected Fonality HUD users.
SIP
DEF07873	Display name portion of the FROM and TO SIP headers are now correctly quoted,
	allowing support for characters such as (, ), [, ]
DEF08132	Phones now support updating the RTP destination when the call is taken off hold –
	this was causing lost voice path on some servers after transfer.
DEF08245	Phones now send an ACK and the call is cleared down correctly when the far-end
	answers the call at the same time that a CANCEL is sent.
DEF08494	Phones initiating the transfer now clear down the transferred call, rather than relying
	on the transferee. This fixes issues with other clients that didn’t clear down the call
	when they were the transferee.
DEF08558	RFC2833 - DTMF support is no longer advertised when the phone is configured to
	only use in-band RTP.
DEF08612	Phones now support updating the Codec when the call is taken off hold– this was
	causing lost voice path after a call was put on hold.
DEF08619	Phones now re-subscribe for SCA and MWI events after receiving a 481 error, which
	can happen after a server reboot.
DEF08632	Phones now clear down a held call on receipt of a 481 in response to an unhold
	attempt or a transfer attempt.
DEF08641	Phones no longer send SDP in the ACK message for calls involving early media.
DEF08649	Phones now support OPTIONS packets within a dialog.
DEF08664	Phones now support Persistent TLS connections using DNS SRV records.
DEF08672	Phones now work correctly behind an ADTRAN TA924E.
DEF08678	Phones now respond to authentication challenges when running behind an
	Edgemarc.
DEF08835	Phones now handle sequence rollovers in SRTP calls correctly.
DEF08836	Phones now include SRTP encryption information in re-INVITE requests.
DEF08846	Phones no longer send a re-INVITE if the user does not enter any more digits after
	receiving a “484 Address Incomplete” response.
XML
DEF07986	Phones now correctly parse XML objects that have a 'space' at the end of a URI.
ENH08004	List objects now support up to 30 items.
DEF09150	FastReboot now works correctly when no language packs installed.
