euro should work fine with the q931 dialect.

What dialect is carried out here?

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: 
+OK
span: 1
type: isdn
chan_count: 24
dialplan: XML
context: default
dial_regex:
fail_dial_regex:
hold_music:
analog_options none
+OK
span: 2
type: isdn
chan_count: 24
dialplan: XML

context: default
dial_regex:
fail_dial_regex:
hold_music:
analog_options none
Again, I'll confer with the big boys and see what other information can be added, or possibly we can create a PRI-specific CLI command like "oz list pri" that shows only PRI spans. Stay tuned for more information...

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):

[EMAIL PROTECTED]> console loglevel 9
[EMAIL PROTECTED]> load mod_openzap
...
[EMAIL PROTECTED]> 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


[EMAIL PROTECTED]> 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?
