[asterisk-users] sip register peer (the quest for near 100% availability)

[XBrian]

Hello. I am aware that 'sip show peers' will display my peers, and that 'sip 
unregister xxxx' (where xxxx is the peer name) will unregister a peer - however, 
I want to force registration of a peer from the CLI.

Is there any way to force this? I have several user agents and I want to achieve 
near 100% availability for all peers. I realise that the peer will be 'woken' up 
at my qualify intervals, but can I actually force registration from the CLI?
