Summary:                    [patch] Realtime erase username when Unavailable
Description: 
When an extension sip become unavailable, the realtime clears the username
within the database. Logs below:

res_config_mysql.c: MySQL RealTime: Update SQL: UPDATE sip SET fullcontact
= '', ipaddr = '', port = '', regseconds = '0', username = '', regserver =
'' WHERE name = '341400'

The right would be (without username column):

res_config_mysql.c: MySQL RealTime: Update SQL: UPDATE sip SET fullcontact
= '', ipaddr = '', port = '', regseconds = '0', regserver = '' WHERE name =
'341400'

Upon further review, It appears that the username is used when sending an
INVITE to a non registered peer.  I am uploading patches (one for each
supported asterisk version) that should preserve the username when a peer
becomes unavailable.
