SIP Station Failover

[bankingguy]

I want to force a few station to register to a local BSM. I tried forcing to unregister the SIP extensions in the Core SM but unable to. What is the best practice to test an SIP LSP site.

i have 1 G450, BSM and CM - 8.x

well, the phone should always be simultaneously registered to 2 core SMs and the BSM.

If you're going to disable NR registration in CM to force the gateway over to the LSP, you might want to use the SIP firewall and blacklist the subnet on the core SMs for the phones. That'll make the core SMs not answer any SIP messages to those phones and force them to use the LSP.

Ok when adding a new rule there are 2 selection, SM and BSM. Can i say if i will use SM and put the remote ip phones subnet on blacklist, does this mean im NOT allowing it to register to SM and just register to BSM? I'm just confuse whats the difference and how it will be applied.

There are rule sets your define for core SMs and for BSMs

You'd make a rule for Core SMs. Once you make that rule, you need to apply it to the 2 SMs in question in their SIP Entity page I believe
