Dahdi - Trunk no audio on out bound

[womble1]

I have copied the above and
my dahdi_channels.conf file is as below…

and did dahdi restart…

odd thing is there is no sound at all not even a ring tone….

This section here tells us the order of the loading of the config files.

The last two lines tells us that channel 1 is being configured twice. So if you actually post all 4 of your chan_dahdi config files exactly as they are, I could help you.....

thanks....

[blanchae]

Okay now the problem is clearer.

In chan_dahdi.conf,

1. remove these lines:

context=from-dahdi
callwaitingcallerid=yes
callerid=asreceived
hidecallerid=no
group=0
channel => 1

Reason: Configuring channel 1 more than once - it shouldn't be configured in chan_dahdi.conf

2. Change

#include chan_dahdi_groups.conf

To

#include dahdi-channels.conf

Reason: chan_dahdi_groups.conf is incomplete (missing group settings) while dahdi_channels.conf is complete.

Stop asterisk and restart. Hopefully now you should have some audio.

 

[womble1]

Ok I have correctly done that restarted the whole box and still no outgoing audio, not even a ring tone… nothing…

seemingly set up OK but on outgoing calls there is no audio

Do you have a trunk configured in FreePBX? Do you have an Outbound route setup to use the trunk?

 

[womble1]

yes,
it rings and the call comes into a mobile or landline, but no audio...

 

[blanchae]

This is what the beginning of my chan_dahdi.conf has:

;
[channels]
;
context=from-pstn
signalling=fxs_ks
rxwink=300 ; Atlas seems to use long (250ms) winks
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=no
faxdetect=incoming
echotraining=800
rxgain=0.0
txgain=0.0
callgroup=1
pickupgroup=1
;Uncomment these lines if you have problems with the disconection of your analog lines
busydetect=yes
busycount=3
hanguponpolarityswitch=yes
immediate=no

It's a little bit more than yours. I would add the extra lines in then restart dahdi.

 

[blanchae]

Here's two tips I found by googling:

answeronpolarityswitch=no
callprogress=yes

 

[womble1]

OK,
I have sip trunk working on an outbound route and have sound on that.
I have done everything and still no sound on outbound Dahdi calls….

 

[Alex728]

Try removing this and see what happens..

answeronpolarityswitch=yes

 

[womble1]

Well,
That did it…
Thanks...

 

[womble1]

How do I get the UK caller ID in ?

 

[Alex728]

Well,
That did it…
Thanks...

happy to help - I found this out the hard way a while back.

Even if your line does gives polarity rev on answer (usually businesslines and featurelines) settring this option makes things go pearshaped.

And you can get different protocols from different lines connected to the same Telephone Exchange!

As for CLID, I'm assuming you have already checked the line with a working phone.

This is what I have in my zapata.conf file which works

usecallerid=yes
cidsignalling=v23
cidstart=polarity
hidecallerid=no

check your Asterisk CLI though, to make sure that Asterisk isn't answering two calls for one.. When you have a line with active called ID, there is a polarity rev before the first ring.

if you get "timed out waiting for ring" after this and a second call coming in for each single call, there is a hack you might need to make to source code to get the CLID picked up. It is only required on some BT lines, not all.

if you need this it might be a bit more difficult for me to find it in chan_dahdi.c as I don't have the source directly saved on any of my machines, unless some helpful person can point me to (I think) the svn repository wherever Digium allow you to look at other versions of source code...

 

[blanchae]

That's really strange that removing "answeronpolarityswitch=yes" works while "answeronpolarityswitch=no" doesn't. Going to have look at those commands in greater depth.
