We have netwokr of CUCM 7.0 and 7921, 7975, 7965, and 7945 phones, connected to internet through ASA firewall
I want to connect my 7921 wireless phone from any public hotspot connect to internet , register with my internal CUCM
I think this can be done via Phone proxy feature on the ASA
Do I need the H/W Security Key (KEY-CCM-ADMIN-K9 ) for my CUCM ?
Any one can help me with sample configuration
