[cisco-voip] IP Communicator and MAC Addresses.

[Craig M Staffin]

What we do is actually force it to use the device name of the wired NIC.
There are two options under the screen in IP Communicator one is for useing
a device and one is for useing a device name.  Tell is to use the device
name and setup the MAC address of the local NIC as SEP.......  Then go into
call manager and configure that MAC as a phone.

This has worked great The only problem we have found is that if someone
disables the local NIC IP Communicator has some problems and says that it
can not open media.

I had thought about this as well, not just about laptop with wired or
wireless, but also with home PC - you'd need a different device for each. I
was thinking about a phantom MAC address that you could program and
configure the client with. Problem with that is, you would have to make
them random enough to (a) not interfere with actual MAC addresses and (b)
not be easily guessed. Since there is no security with IP communicator, all
you need to do is configure your client with someone else's MAC address and
you login with their phone.

If someone has found a workaround to this little bug, or if I am totally
off the wall on this, please, let me know!

 Subject: [cisco-voip] IP Communicator and MAC Addresses.

 I am having a problem with the IP Communicator; my problem is that it is
 registered to the MAC Address of the LAN NIC Card on a laptop. If the
 person that uses this laptop wants to use his/her wireless card then it
 does not see it as being registered because it is a different MAC.

 Does any know of a work around for this, I thought of maybe putting 2 for
 each laptop in Call Manager with a shared line but it seems to me there
 should be an easier way.


 Thanks,
 Danny
