HELP !!!! I can't configure a sip line on cisco phone cp-7841 (without CUCM, Expressway)

[Jc Mtz]

Good day I have 3 ip telephones cp-7841, they were reset default but when starting 
the phone I see a screen with the following data:

Service name:
User ID:
Password:

I can not access via the web even if the phone already has ip by dhcp, 
I do not have CUCM or EspressWay, is it possible to configure a sip line 
on these phones without those systems ?? '

 

First of all, Thanks

Do you have the cp-7841-3pcc or cp-7841-k9 model? And are you trying to make the phone a stand-alone device without a call processor, or will it be registering to a 3rd party call agent?

The CP-7841-K9= phone model is for use with Cisco call control, like CUCM. For 3rd party call control systems like Asterisk, the correct model is CP-7841-3PCC-K9=.

Compare this (CP-7841-K9=):

Sorry... You have the wrong phone model for what you want to do.
