Title: Incoming call fail on 5312 phone with 3rd party server
Post by: Den Li on July 20, 2018, 04:32:43 AM

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
