Hello!
I use asterisk with TE420 as PRI switch for two channels :
;panasonic uplink
group=3
context=panasuplink
; relaxdtmf=yes
; immediate=yes
rxgain=0.0
txgain=0.0
mohsuggest=default
jbenable = no
; jbenable = yes
; jbmaxsize = 200
; display_send=name_initial
display_send=name
display_receive=name
; display_receive=
channel=>63-77,79-93
;panasonic
group=4
priindication = outofband
rxwink=300
pridialplan=unknown
prilocaldialplan=unknown
context=panas
rxgain=0.0
txgain=5.0
; signalling=pri_net
switchtype=qsig
overlapdial=yes
resetinterval=never
immediate=no
mohsuggest=default
jbenable = no
; jbenable = yes
; jbmaxsize = 200
; display_send=name_initial
display_send=name
display_receive=name
; display_receive=
channel=>94-108,110-124
Initially I had no txgain=5.0, but users complains that they hear not
as good as before asterisk was added into this scheme.
We even tested and found that yes, asterisk decreases volume.
Could you tell me why? As I understand this is digital connection and
there is the same alaw codec, so no trancoding.
Why can be sound volume changed during chan_dahdi native bridging?
Thank you!
