I am new to setting up SER and this is the test setup.

1. DHCP running from router

2. SJ Phone on laptop 192.168.X.X

3. Grandstream Budgetone 101 192.168.X.X

4. SIP Express Router 192.168.X.X

5. Asterisk Server 192.168.X.X attached to tdm400p card is an analog phone

Will this work internally? There is no connection to a telco.

The SJ phone is showing the following: nat/firewall: Port Restricted Cone NAT

SIP calls use outbound proxy: 192.168.X.X (SER)

Will I have to register the SJ, Grandstream and Asterisk PBX?
