Get registration details from Asterisk DB SIP3 :: THe registry database (astdb)

The SIP3 registry database contains a string that contains fields separated by | characters. When a device registers, the string is stored to the database in order to allow restarts of Asterisk without loosing data. When Asterisk restarts, the SIP channel loads data from the ASTDB "sip3-registry" family in order to populate the peer list with registered peers.

Fields:

Expirytime: The time (unix time) when this registration expires
IP address: Registered IP address or NAT address
Port: Registered port our NAT port
Expiry: How long this registration is valid
Contact: The Contact header registered with Asterisk

Functions:

reg_source_db()

A problem with this is that if Asterisk has not been running for more than 30 secs, we might not be able to keep NAT relations alive and will send out keepalives that will be refused by the NAT. The device will quickly become UNREACHABLE until we get a new registration from the inside.
