Reload chan_sip.so

Hi, using asterisk 1.6.2.8. Does a module reload of chan_sip.so destroy
all current registrations with VoiP providers ie those created with register=>
or just the ones that changed. I am going to change the sip.conf red from a database
and then do a reload so i need to know what happens to existing registrations.

Thanks

if u change sip.conf reload it than old configuration will be lost…so it is best to make a backup copy.

thanks
