Hi,
 
Is there a log option to turn on logging of SIP registration messages ?
 
I have a mixture of phones and am having a problem with some of them periodically losing registration with FreeSWITCH.
 
All the phones start off working after provisioning and have registration expiry times configured of 3600 seconds.
 
I have tried changing the expiry time to no effect and I wanted to see if the phones were actually trying to renew the registration when they should.
 
Regards
Dave
