I Have a requirement to setup a CUBE inbetween some 3rd party SIP phones and their registrar server.
According to the documentation I need to configure the Cube to support SIP Registration Proxy.
The following steps are required for this configuration
Configuring Support for SIP Registration Proxy on Cisco UBE
•Enabling Local SIP Registrar (required)
•Configuring SIP Registration at the Global Level (required)
•Configuring SIP Registration at the Dial Peer Level (required)
I would like to know if this is the correct approach.
I would also like to understand the dial-peer configuration in this case.
Am I to create two dial-peers? One for outgoing and one for incoming?
If so, how would the incoming dial-peer look like? As I do not have a trunk configuration towards each phone. The Phones get IP's assigned via DHCP.
According to the documentation I need to create a dial-peer with session target registrar
This does not seem to be a supported option in my ver 15.1(3)T
Can anyone provide me with a sample config for this scenario?
