Please bear with me. I'm brand new to IP telephony. I have a Cisco 8811 that I'd like to use with a service like Call Centric. I THINK I understand what's possible, but perhaps not...
Can someone please point me to the basics of using this IP phone with a virtual PBX service that will provide me a dial tone? I want to, without using a pbx (I have just this one phone), be able to place and receive calls by having the phone directly connect to an internet phone service provider.
This may not even be possible, since I read a post here that said if an 88xx comes with enterprise firmware (which I think my phone may have), it cannot be converted it to 3PCC, which I believe is necessary to do what I am trying to do.
As you can see, I have no idea what I'm doing yet, and pointers to any basic sources of info or tips would be greatly appreciated.
Thank you for the responses.
As a model number, I see "CP-8811", and in the "active load" field, I see "sip88xx.12-1-1SR1-4". Does this shed light on whether it has enterprise firmware?
Thank you. Will this allow me to revert to 3PCC firmware?
If the phone is running Enterprise firmware then it will NOT be possible to load 3PCC firmware.
