[Asterisk-Users] Data over Voice through Asterisk

[Andrew Yager]

Hi,

I'm trying to make a dialup internet connection through my asterisk 
PBX. When I bipass the Asterisk box, I can get 51600bps. When I run 
through the asterisk box, I'm limited to about 21600bps.

I have a TDM31B card.

Any help on speeding these connections up would be good - I was on the 
understanding that if you bridged the channels, then the call should 
essentially flow straight through, uninhibited or interrupted?

Thanks in advance,
Andrew


My zapata.conf file is:

[channels]
context=incoming
signalling=fxs_ls
rxwink=300              ; Atlas seems to use long (250ms) winks
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
callreturn=yes
echocancel=no
echocancelwhenbridged=no
;echotraining=yes
rxgain=0.0
txgain=0.0
group=1
callgroup=1
pickupgroup=1
immediate=no
busydetect=yes
busycount=4
musiconhold=default
switchtype=national
channel => 1

context=local
signalling=fxo_ls
channel=>2

-> this is the output from the various zap commands at the asterisk CLI
