Basic help needed for Cisco 8811

Hello

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!

-John

What I'd like to know is if the phone came with 3PCC or Enterprise firmware.

Yes, would be more curious to know your current model of phone and the firmware. To get multi platform PBX support on an 8811 you need to purchase the 8811- 3PCC SKU.

Hope this helps

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?

Yup! That’s an Enterprise phone. Means it’s for CUCM registration. If you can see the firmware name contains MPP that indicates it’s got a 3rd Party Phone Control firmware. Unfortunately you can’t convert an Enterprise loaded firmware phone to 3PCC Phone. Whereas you can upgrade from Third-Party Call Control to Enterprise Firmware but after you upgrade to the Enterprise Firmware, you cannot revert to the Third-Party call control firmware.


Hope this helps

Now why in the world does Cisco not allow you to change from enterprise to 3PCC?  It seems like a really bad decision.

Another question: Can I use Asterisk as a PBX with this phone, or does it absolutely require CUCM to talk to?

Thanks

 

Hi there

I have read some posts that you can use the enterprise phones with Asterisk PBX using the same firmware

Go HERE for a known working configuration file for a 9951/9971.  

Please don't forget to rate our useful posts.

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.
