Unique MAC address for Mobile Broadband CardsLocked
Question: In order to create a unique MAC address for Mobile Broadband PCMCIA Cards, how do I substitute or change the MAC address on Mobile Broadband Cards?
Goal: Establish multiple remote site connections to Central Office VOIP system using Mobile Broadband Cards and Softphones.
Roadblock: Mobile broadband cards (PPP/SLIP interface)use the same Mac Address (Verizon, Sprint, AT&T)i.e. 00-53-45-00-00-00.
Since my VOIP system uses the MAC address to register the softphones, and since my remote sites are connecting to our VPN/VOIP system using mobile broadband cards, they all display the same MAC address.
This is not a problem connecting to the central office vpn but I am able to register only one softphone at a time to the VOIP system. When I try to register the second remote softphone, it either replaces the first softphone registration or registers both softphones to the same phone number creating garbled communication. This is due to the same MAC address on the mobile broadband card
HW/SW: Panasonic VOIP card and Softphones, Sprint Novatel S720 Mobile Broadband Cards, WindowsXP operating system, Netscreen Remote VPN Client.
I’ve tried: Making changes in registry key 4d36e4972-e325-11ce-bfc1-08002be10318 (no sub key exists for the M B card), MAC address spoofing software, non-responsive sprint, panasonic and novatel technical support, changing virtual adapter settings on vpn client.
I have hit the wall, but am not ready to give up yet. Any suggestions or direction would be greatly appreciated.
