Summary:                    DIGITAL calls across a B410P connect, but no data
transfer
Description: 
When placing calls from port 1 of a B410P to port 2, the call appears to
connect, but not data transfers.

Both ports are set to NT mode, with terminating resistor switched on.

dialplan code:
exten => _82XX,1,Dial(DAHDI/g4d/${EXTEN})

As discussed with mattf on IRC
effectively disable all cards except B410P, I've physically removed them.
set echocancel=no and echocancelwhenbridged=no in chan_dahdi.conf
 
To get it working the fix was chan_dahdi.conf: echocancelwhenbridged=no

otherwise if "echocancelwhenbridged=yes" using 'dahdi show channel x'
 inbound leg, channel 1, has echo turn off, this is good.
 outbound leg, channel 4 has echo turn on, not good.

file chan_dahdi.conf below works.

context=incoming
pridialplan=unknown
prilocaldialplan=unknown
facilityenable=yes
transfer=yes

switchtype=euroisdn
signalling=bri_net_ptmp
overlapdial=yes
immediate=no
echocancel=yes
echocancelwhenbridged=no
group=1
channel => 1, 2
group=2
channel => 4, 5
group=3
channel => 7, 8
group=4
channel => 10, 11

dialplan:
[incoming]
exten => _81XX,1,Dial(DAHDI/g1/${EXTEN})
exten => _82XX,1,Dial(DAHDI/g2/${EXTEN})
exten => _83XX,1,Dial(DAHDI/g3/${EXTEN})
exten => _84XX,1,Dial(DAHDI/g4/${EXTEN})
