lg/nortel 1535 - phone does not recognize succesfull transfer

[david l]

when transferring callers, the transfer completes successfully, BUT the phone does not realize this !
When using blind or consultation transfer after the transfer has completed successfully the phone still gives options to take the call off hold or resume and pressing buttons has no effect.

Using phone menus to transfer call.

Note: the menus also do not work for conference (http://pbxinaflash.com/community/threads/nortel-1535-transfer-canceled.8918/)
