I am trying to connect a CP-8851-K9 to a Mitel IP CXii PBX. I am using the sip88xx.11-0-1SR1-2 firmware, but the phone is not registering with the PBX. All what I see is detecting Network. I can see that the phone is getting a valid IP, able to ping the PBX, but not registering. How can I get the phone logs to see what is happening?
