How connect IP Phone 7960 with AS5350 without CCM or SIP ?


HI ALL !!!

PLZ, help me !

I think this is Cisco IP Keyswitch.

But the question - whether it will work, if 5350 and 7960 are in different cities, and certainly in completely different subnets, divided alied routers, and by the document from link, 7960 address receives on DHCP from 5350.

As far as I remember DHCP works only in the LAN.

Whether means in my case to connect these devices it is impossible?

So I understand?

Thanks ALL !

The ip keyswitch is supported only in 1750,1751,2600,3600, 3725,2745 and IAD 2420. In case that you use one of this routers, you can use the command "ip helper-addres" to resolve the issue about DHCP ( its works in lan enviroments), this command redirects all the local broadcast to a unique ip address ( your router, in another network).
