To use the Nx70 behind an Cisco platform, there are 3 options:

1. As SIP device direct registered to Cisco (Not supported)
2. As SIP device via "anynode"
3. Via an SIP trunk

1. As SIP device direct registered to Cisco

It is not possible to use N870 behind Cisco connected as SIP device, due to the fact that Cisco wants to have for each SIP account an separate port, Gigaset Nx70 is using for each SIP account the same port.

Is also an expensive solution as for each DECT handset you need to buy an Cisco SIP device license.

2. As SIP device via "anynode"

Via an anynode SBC, you can register Nx70 to the anynode and anynode will register itself to cisco.

For this anynode knowledge is required including hardware and software.

3. Via SIP trunk (Not valid when using embedded or virtual integrator)

As this is an proven technology with N720, and from now possible with Nx70.

Via provisioning, you can configure the Nx70 to be used via an Cisco SIP trunk.

Advantage:

• No Cisco licenses
• Proven technology
• Easy to configure

Telephony functionality:

• Calls between Cisco desktop phones and DECT handsets
• Call transfer
• Conference call is not supported
