Dear All,
I connected Mitel 5312 phone (SIP mode) with 3rd party sip provider but only outgoing call is working. All incoming call is fail.
I used another Yealink T21 phone connected to same sip provider from same office network. The Yealink phone is no problem
Anything I missed on Mitel phone?! Please help.
Thanks,
Den
