We have added new dialect ( li_ewsd, similar to Q.931, but different that bytes of data SUBADDRES do not mask with & 0x7F -
- so the specifications of telephone stations EWSD & Surpass demands, which place into SUBADDRES special user info ( different
for EWSD & Surpass stations) ).
We have made some changes in libs/openzap/src/isdn/include/Q931.h:
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_li_ewsd = 8, // Coming soon to a PRI stack near you!
Q931_Dialect_Count
} Q931Dialect_t;
#define DIALECT_STRINGS "q931", "", "national", "", "dms", "", "5ess", "", "li_ewsd", ""
After recompilation mod_openzap we connect 2 FreeSWITCH on different hosts with PRI channel through 2xE1.
Then we manage to receive.
[host 1, X-Lite] -SIP-> [host 2, FS] -PRI-> [host 3, FS] -> record_session()
Written *.wav the file is identical to that was told from X-Lite softphone
Записанный *.wav файл идентичен тому, что говорилось из X-Lite softphone...
But periodically ( > than minute ) such messages are output on FreeSWITCH console:
2008-09-18 18:53:47 [WARNING] zap_zt.c:668 zt_next_event() Unhandled event 8
2008-09-18 18:53:47 [DEBUG] zap_isdn.c:790 process_event() EVENT [INVALID][1:16] STATE [UP]
We can suppose, that it because of both sides of PRI channel are configured in such manner
<pri_spans>
<span id="1">
<param name="mode" value="user" />
<param name="dialect" value="li_ewsd" />
....
</span>
- because of "user".
Are we right?

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.

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 at opos8.altron.lan> console loglevel 9
freeswitch at opos8.altron.lan> load mod_openzap
...
freeswitch at 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 at 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?
