I'm following the OBI-VoIP IP Workbook v1.0 guide to configure my Cisco IP phones 7941. I have a question about SIP and the XMLDefault.cnf.xml file. I'm not able to make any changes to the the SIP setting on the IP phones, I do not get the select option at all. Do I need to setup SIP via the XMLDefault.cnf.xml file? If so, do you have a sample XMLDefault.cnf.xml that I can use as reference? I'm really stuck and need some help.
Thank you. I'm new at this so please be gentle
