We have a lot of questions about mod_openzap & PRI.

1. If to see directory libs/openzap/src/isdn it is possible to see, there are defined
such dialects : Q931, national, EvroISDN, DMS, 5ESS.

$ ls *.c
5ESSmes.c DMSStateNT.c mfifo.c Q921.c Q931mes.c
5ESSStateNT.c DMSStateTE.c nationalmes.c Q931api.c Q931StateNT.c
5ESSStateTE.c EuroISDNStateNT.c nationalStateNT.c Q931.c Q931StateTE.c
DMSmes.c EuroISDNStateTE.c nationalStateTE.c Q931ie.c Q932mes.c

Into the file libs/openzap/src/isdn/include/Q931.h (line ~500) are defined only 4 dialects

typedef enum // Dialect enum
{
Q931_Dialect_Q931 = 0,
Q931_Dialect_National = 2,
Q931_Dialect_DMS = 4,
Q931_Dialect_5ESS = 6, // Coming soon to a PRI stack near you!

Q931_Dialect_Count
} Q931Dialect_t;
#define DIALECT_STRINGS "q931", "", "national", "", "dms", "", "5ess", ""

Is it possible to add our own dialect PRI (for another submission of SUBBADDRESS, for example), if we'll add
new files *mess.c, *StateNT.c, *StateTE and definition * into the Q931Dialect_t ?


================================================================================

2. We start zaptel :

# ls /dev/zap
1 12 15 18 20 23 26 29 31 34 37 4 42 45 48 50 53 56 59 61 8 ctl
10 13 16 19 21 24 27 3 32 35 38 40 43 46 49 51 54 57 6 62 9 pseudo
11 14 17 2 22 25 28 30 33 36 39 41 44 47 5 52 55 58 60 7 channel timer

- zaptel is started and configured normally.

Next load FreeSWITCH...

We use such configuration file for mod_openzap :

<configuration name="openzap.conf" description="OpenZAP Configuration">
<settings>
<param name="debug" value="1"/>
</settings>
<pri_spans>
<span id="1">
<param name="mode" value="user" />
<param name="dialect" value="dms" />
<param name="dialplan" value="XML"/>
<param name="context" value="public" />
</span>
<span id="2">
<param name="mode" value="user" />
<param name="dialect" value="q931" />
<param name="dialplan" value="XML"/>
<param name="context" value="public" />
</span>
</pri_spans>
</configuration>


Next we start (from FreeSWITCH console):

freeswitch@opos8.altron.lan (freeswitch@opos8.altron.lan)> console loglevel 9
freeswitch@opos8.altron.lan (freeswitch@opos8.altron.lan)> load mod_openzap
...
freeswitch@opos8.altron.lan (freeswitch@opos8.altron.lan)> oz dump 1 16
API CALL [oz(dump 1 16)] output:
span_id: 1
chan_id: 16
physical_span_id: 1
physical_chan_id: 16
type: DQ921
state: UP
last_state: DOWN
cid_date:
cid_name:
cid_num:
ani:
aniII:
dnis:
rdnis:
cause: NONE


freeswitch@opos8.altron.lan (freeswitch@opos8.altron.lan)> oz dump 2 16
API CALL [oz(dump 2 16)] output:
span_id: 2
chan_id: 16
physical_span_id: 2
physical_chan_id: 47
type: DQ921
state: UP%!
last_state: DOWN
cid_date:
cid_name:
cid_num:
ani:
aniII:
dnis:
rdnis:
cause: NONE

In what manner ( using console or debugging messages ) we can see in run-time mode under what type of a dialect
every "span" is configured ?

If we'll specify for nonexistent dialects:

<pri_spans>
<span id="1">
<param name="dialect" value="ABC" />
</span>
<span id="2">
<param name="dialect" value="XYZ" />
</span>
</pri_spans>

- then >load mod_openzap is carried out successfully and >oz dump <i> <j> gives us same result like before.

What dialect is used by "span" in this case? How it can be looked?

[msc at freeswitch.org]

Evgeniy,

I'm not sure why EuroISDN isn't listed in the enum or string below because I know that Stefan (stkn on IRC) has been working on it for some time. I'll follow up with him and Mike Jerris to see what's going on there.

As for seeing the dialect at run-time, right now you can't, although I don't see what that functionality can't be added. Most likely you'll need to use the "oz list" CLI command which gives output like this:

[anthony.minessale at g...]

the dialects are not all done. we so far can do DMS100 and euro

please join #openzap on irc.freenode.net and join the effort.

Thanks for all. But I am in perplexity now - how we can khow, what any certain dialect is carried out?

Look for this example:

[mike at jerris.com]

euro should work fine with the q931 dialect.

[zolotov at altron.ua]

Thanks, Mike. But what dialect works when we make

<param name="dialect" value="ABC" />

or

<param name="dialect" value="XYZ" />


How we can define it ????????????????????????
(See example below)

[mike at jerris.com]

my guess would be that it just fails to load. what does the debug say?
