Monitoring SIP-UA and do actions "reload" or "re-register SIP-UA"

[sSiDs]

Hi team! Need your help in fine tuning EEM.

025951 is registered to registrar1 and 036751 to registrar2

everything works fine...exept SIP registration 025951 could be dropped ... suddenly, without any reason

ssip - alias to "sh sip-ua register status"

ssip runs every 300 seconds to verify that 025951 is registered to Registrar-Index 1

i do not know which way is better and do not know HOW TO configure:

scenario1: If 025951 is dropped in Registrar-Index 1, then reload router.

scenario2: If 025951 is dropped in Registrar-Index 1,remove all SIP-UA config and configure againg.

I am appreciate for any help!

I thought I replied to this already, but I guess CSC didn't take it.  You don't need a lot of the complexity you have here.  This applet should work for you to reload the device.  If you'd rather reconfigure sip-ua, you can add the cli actions instead of the reload action.
