Asterisk Database (AstDB) Database data are grouped in families and identified with a key that is unique within the family. AstDB’s structure is similar to the following: Family1 Key1 => value Key2 => value : Keyn => value Family2 Key2 => value

Asterisk Database’s Applications Applications: DBput DBget DBdel DBdeltree Dbput Stores value in the database Dbput(family/key=${foo}) (deprecated) Set(DB(family/key)=${foo}) (new syntax) CLI Command CLI*>database put family key

Asterisk Database’s Applications Dbget Retrieve a value from the database Dbget(foo=family/key) (deprecated) Set(foo=${DB(family/key)}) CLI Command CLI*>database get family key Dbdel Delete a key from the database Dbdel(family/key) CLI Command CLI*>database del

Asterisk Database’s Applications Dbdeltree Delete a family or key tree from the database Dbdeltree(family/keytree)

Call Forwarding Forward the incoming call to some other number, or forward the incoming call to some other number in case of busy or unavailable Two types of abbreviations are used: Call Forward IMdiate (CFIM) Call Forward on BuSy (CFBS)

Call Forwarding An example of call forwarding: [apps] ; ; Unconditional Call Forward ; ; create call forward exten => _*21*X.,1,GotoIf($${EXTEN:-1} = #?2:3) exten => _*21*X.,2,StripLSD(1) exten => _*21*X.,3,DBput(CFIM/${CALLERIDNUM}=${EXTEN:4}) exten => _*21*X.,4,Hangup ; ; delete call forward exten => **21,1,DBdel(CFIM/${CALLERIDNUM}) exten => **21,2,Hangup ; ; delete call forward (with #) exten => **21#,1,Goto(**21,1)

Call Monitoring Taps into a phone call between a caller and a callee. This is possible with: ChanSpy() ZapBarge() ExtenSpy() Example While spying Dialing # cycles the volume Dialing * will stop spying and look for another channel to spy on

Call Monitoring ZapBarge() Listens in on a conversation on a zap channel. If a channel is not specified, it will prompt for one Example Exten => 8159,1,ZapBarge() Exten => 8159,2,Hangup() If you dial 8159, you are asked which line you want to listen on; for zap/1-1 you will press 1# and for zap/25-1 you will press 25#

Call Monitoring ExtenSpy() Listen in on a channel, and also whisper into it if necessary Example [snoop] exten => _555/705,1,ExtenSpy(|v(4)) [705] exten => 705,1, dail(IAX2/trunk_3) include => snoop

Call Monitoring Add the following lines in extensions.conf exten => *898,1,Answer exten => *898,2,Wait(1) exten => *898,3,Goto(spy,s,1) exten => *898,4,Hangup [spy] exten => s,1,BackGround(please-enter-the) exten => s,n,BackGround(extension) exten => s,n,Set(TIMEOUT(digit)=5) exten => s,n,Set(TIMEOUT(response)=10) exten => s,n,WaitExten(10) exten => _XXXX,1,ChanSpy(SIP/${EXTEN}|q)

Call Transfer Transfer a call-in-progress to another destination. There are two types of transfers: Supervised Call Transfer Blind Call Transfer Features.conf settings: blindxfer => #1 disconnect => *0 atxfer => *2

Call Parking Places a call on-hold onto a specific parking location so that it can be picked up by another extension Features.conf Parkext => 700 Parkpos => 701-720 Context => parkedcall Parkingtime => 45

Route by Caller ID exten => 123/100,1,Answer()    exten => 123/100,2,Playback(tt-weasels)    exten => 123/100,3,Voicemail(123)    exten => 123/100,4,Hangup()
