SIP/MGCP/H323 terminals are deployed at public network, and Eudemon2100 is set to a proxy, but they cannot register at SoftX3000.
1. Trace the network messages at both upstream and downstream interface of Eudemon2100 respectively, and it is found Eudemon2100 has received the registration message from the peer, but it does not reply any message to SoftX3000.
2. Turn on the debugging switch of Eudemon2100
deb sbc sip packet
deb sbc sip reg
deb sbc am error
The address binding is enabled, and the registration of the terminal is denied.
3. Execute undo sbc roamlimit enable command to cancel the binding.
4. The terminals can register at SoftX3000 successfully. The problem is solved.
Eudemon2100 is configured with address binding, but the terminals not. By default, the address binding denies the registration of users.
