Hi All,
I have encountered a problem.
My SIP phone was registered to Mitel 3300 server.
During talking with the 1st far-end, I pressed FLASH key with my phone (i.e. an INVITE (sendonly) msg is sent) and dialed the 2nd call. However, I found that after my phone sending out the INVITE msg for the 2nd call, I received a strange BYE msg from Mitel 3300 (not the 1st far-end) to kill my 1st call. As a consequence, my 1st call is dropped, so that I never do Conference or resuming the 1st call.
Any there any suggestion for me? Does my phone need to do sth special?
THANKS!!!
