Libss7, Dial-in, rings and gets answered but no voice

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Dear All,

I am not sure if I can post this here or I should start a new thread but
here goes...
I setup Libss7 with asterisk 1.6 , linkset is UP, I can make successful
outbound calls , I can hear the other party well.
Now the odd thing is that when someone tries an inbound call , the call gets
connected but they hear nothing I tried setting up MOH, I also tried to
record the incoming call but I hear nothing.
Is anyone facing such an issue, will you please help me shed some light on
this issue.

Thank you,
Ziad

Thank you very much. I didn't saw there are two separate vars

The other side is set to inband as it is dedicated to alarms (both ATA and
Asterisk) - no need to change the mode, but only 50% of the calls were
working with Asterisk (with lowered dtmf detection durations in the code)
and a bit more on the hardware receiver. Will test now with
DAHDI_IGNORE_INCOMMING_DTMF_DETECT on the gateway. Thanks again!

network routed is matched before subscriber - set
"ss7_networkroutedprefix=NA", so it wont match on blank

maybe it will be better to check in the code for non blank prefix? Or it
will break some other logic?

You will need to change also unknown prefix, as it will match next

yes, i know for this, i tryin to set subscriberprefix before
ss7_called_nai and everithing, option was first in this context like this:



language=en
context=from-btk-fix
switchtype=euroisdn
usecallerid=yes
callwaiting=yes
usecallingpres=yes
signalling=ss7
group=3
ss7type = itu
ss7_explicitacm=yes
ss7_autoacm=yes
ss7_subscriberprefix=112
ss7_called_nai=dynamic
ss7_calling_nai=national
ss7_nationalprefix=0
ss7_internationalprefix=00
ss7_networkroutedprefix=iwillnotusethisnai
linkset = 3
pointcode = 5176
adjpointcode = 121
defaultdpc = 118
networkindicator=national
cicbeginswith = 1
channel = 63-77
cicbeginswith = 17
channel = 79-93
sigchan = 78
isup_timer.digittimeout = 500

but nothing , :(
If i set ss7_called_nai = subscriber, everithing is ok, but
in this situation every call is with called_nai = subscriber.....:(

What i need to do , i dont know.....
