What should 'dahdi show channels' show?

sdbrehm · June 19, 2012, 6:09pm

I’d like to see all the active calls in one display. When I execute ‘dahdi show channels’ I get

Chan Extension Context Language MOH Interpret Blocked State
pseudo default default In Service
1 from-pstn en default In Service
2 from-pstn en default In Service
3 from-pstn en default In Service
4 from-pstn en default In Service
etc…

It only appears to list incoming calls. Is this because the Context is ‘from-pstn’? What is the default supposed to be. Just that? All contexts? I’ve tried various alternatives using the context parameter, ie ‘dahdi show channels context from-internal’ and get no output lines at all.

The first number is a port, the second field is the context used for inbound calls. It should display a call on the port no matter if it is originating or terminating.

Perhaps I’m not getting the terminology. You say inbound calls can be either originating or terminating. I think of inbound as a call coming to my system through a PRI and terminating at my system. I think of originating as meaning leaving my system and going out the PRI, but I’d call that outbound not inbound.

Your terminology is correct. And you should see both originating and terminating traffic.

Each line is the status of a channel. The actual point the call started at is irrelevant from a DAHDI/channel perspective.

Any idea why I’m only seeing calls that are terminating on my system? BTW, our PRI provider passes the last four digits of the number the outsider dialed and I do see those digits in the extension column of dahdi show channels.

I find it hard to believe that you are not seeing the traffic.

Send a short log snipet. I bet the traffic is not going out the PRI.

This is from a call I placed yesterday to a test number.

Ok, are all your PRI channels in group 0?

So after this call is answered what is the output of dahdi show channels and sip show channels. I want to see both.

sdbrehm · June 20, 2012, 4:31pm

Here you go. I’ve got three zap identifiers g0, g1, and g2 defined for three PRI’s. One outbound route with the three PRIs in that order. From chan_dahdi.conf:

; Span 1: TE2/0/1 “T2XXP (PCI) Card 0 Span 1” (MASTER)
group=0,11
context=from-pstn
switchtype = national
signalling = pri_cpe
channel => 1-23
context = default
group = 63

; Span 2: TE2/0/2 "T2XXP (PCI) Card 0 Span 2"
group=1,12
context=from-pstn
switchtype = national
signalling = pri_cpe
channel => 25-47
context = default
group = 63

; Span 3: TE2/1/1 "T2XXP (PCI) Card 1 Span 1"
group=2,13
context=from-pstn
switchtype = national
signalling = pri_cpe
channel => 49-71
context = default
group = 63

I can use groups 0,1,2,11,12,and 13 in the dahdi show command to filter the output to the related channels.

Here is that output during a test call:
