Aastra 6739i SIP Phone Firmware 3.3.1.2217

Fixes:

- An issue with certain parameter type definitions caused an ACS inventory error. This issue has been corrected.
- When using the phone with the Clearspan Assistant toolbar, adding a fourth participant to a conference call would connect all participants as expected, but the conference would continue to be placed on hold with no way of retrieving the conference. This issue has been fixed.
- When using the phone in conjunction with the EdgeMarc Session Border Controller(SBC) in LOCAL MODE, an issue was observed whereby the phone would respond to incoming calls with a 404 Not Found response. This issue has been corrected. 
- An issue was observed whereby the phone did not request the URI defined within the “action uri xml sip notify” parameter when the call manager sent an empty SIP NOTIFY request. This issue has been resolved
- With two phones sharing a line configured with SCA functionality and the SCA bridging feature enabled, if one of the phones dialed out (with Live Dialpad enabled) when the other phone was in an active call, the two phones would unexpectedly be bridged. This issue has been fixed.
- If an incoming call was terminated immediately after being received, a short delay in ending the call and releasing the line could at times be observed. This issue has been corrected.
