; Caller ID routines/signalling
; For FXO ports, select one of:
; on = collect caller ID between 1st/2nd rings using VPB routines
; off = do not use caller ID
; bell = bell202 as used in US, using Asterisk's caller ID routines
; v23 = v23 as used in the UK, using Asterisk's caller ID routines
; For FXS ports, set the channel's CID in '"name" <number>' format
;
; NOTE that other caller ID standards are supported in Asterisk, but are
; not yet active in chan_vpb. It should be reasonably trivial to add
; support for the other standards (see the default chan_dahdi.conf for a
; list of them) that Asterisk already handles.

; Use a polarity reversal as the trigger for the start of caller ID,
; rather than triggering after the first ring.

; Use loop drop to detect the end of a call. On by default, but if you

; Use in-kernel bridging. This will generally give lower delay audio if
; bridging between two VPB channels. It will not affect bridging
; between VPB channels and other technologies.

; Software transmit and receive gain. Adjusting these will change the
; volume of audio files that are played (tx) and recorded (rx). It will
; _not_ affect audio between channels in a native bridge. It will,
; however, affect the volume of audio between VPB channels and channels
; using other technologies (such as VoIP channels). Usually it's best to
; leave these as they are. If you're looking to get rid of echo, the
; first thing to do is match your line impedance with the bal1/bal2/bal3
; settings.
;
;txgain=0.0
;rxgain=0.0

; Hardware transmit and receive gain. Adjusting these will change the
; volume of all audio on a channel. The allowed range of settings is

; Balance register settings, for matching the impedance of the card to

; Ring groups (a.k.a. call groups) and pickup groups. If a phone is

; If we haven't had a "grunt" (voice activity detection) for this many

; Type of line and line handling. This setting will usually be overridden
; on a per channel basis. Valid settings are:
; fxo = this is an FXO port
; immediate = this is an FXS port, with no dialtone or dialling
; required (ie it is a "hotline")
; dialtone = this is an FXS port, providing dialtone and dialling
