Channels * B410P ISDN Card

Asterisk Asterisk Support
1

I have an new Asterisk installation with a TDM400P (2 x fxs, 2 x fxo) and a B410P ISDN Card.

I have Centos v4.4, zaptel 1.2.12, asterisk 1.2.14, libpri1.2.4, addons 1.2.5 and sounds 1.2.1

I have successfully installed the driver and the green light comes on the and I get sync on the Telsta ISDN Box. I can successfully receive calls but i can only make a single outgoing call. Currently i only have 1 port configured and connected but each port has 2 channels so i should be able to make 2 calls. I can make a call and receive a call at the same time and can receive 2 incoming calls but not make 2 outgoing calls. This indicates to me maybe i havent set something in Asterisk. Here are the releveant config files

/etc/misdn-init.conf

card=1,0x4
te_ptp=1,2,3,4
poll=128
dsp_options=0
debug=0xf

/etc/asterisk/misdn.conf

hdlc=no

[line1]
ports=1ptp
context=from-pstn
msns=*

[line2]
ports=2ptp
context=from-pstn
msns=*

For the TDM400P I have the following configs

/etc/zaptel.conf
loadzone=au
defaultzone=au
fxoks=1-2
fxsks=3-4

/etc/asterisk/zapata.conf

[trunkgroups]

[channels]
context=default

signalling=fxo_ks
language=en
context=from-zaptel
group=0
channel=1

signalling=fxo_ks
language=en
context=from-zaptel
group=0
channel=2

signalling=fxs_ks
language=en
context=from-zaptel
group=0
channel=3

signalling=fxs_ks
language=en
context=from-zaptel
group=0
channel=4

switchtype=national

I have no config in teh zapata.conf for my ISDN interface but from what Ive read you no longer need it.

Can any1 assist as to why I cant make 2 outgoing calls at once?

Do i need to set channels somewhere to indicate that I have 2 channels per port??

Thanks in advance,

Daniel.

i haven’t played with mISDN yet, but from a quick glance, wouldn’t it be [line1] ports=1,2 context=from-pstn msns=* ??

Can be done that way as well.

Originally i had :-

[line1]
ports=1,2,3,4
context=from-pstn
msns=*

but im just working on one port at the moment to try and get it to work.

This has no bearing on why the 2nd channel is not being used but thanks for the reply.

can you show us the dialstring you’re using ?

The string is :-

mISDN/g:line1/$OUTNUM$/:s:e128

Can anyone provide any assistance with this. When you purchase a Digium Card, Digium say they will help with the installation but I have yet to receive a response from them.
