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?_______________________________________________
