[Freeswitch-dev] mod_openzap and PRI from users-list

[Evgeniy Zolotov]

Here is how it is to see really used dialect for span:

1. To write down erroneous /etc/openzap/openzap.conf - nonconsistent trunk_type

$ cat /etc/openzap/openzap.conf
[span zt]
name => OpenZAP
number => 1
trunk_type => Z1
#trunk_type => E1
b-channel => 1-15
d-channel => 16
b-channel => 17-31

[span zt]
name => OpenZAP
number => 2
trunk_type => Z1
#trunk_type => E1
b-channel => 32-46
d-channel => 47
b-channel => 48-62

[span zt]
name => OpenZAP
number => 3
trunk_type => Z1
#trunk_type => E1
b-channel => 63-77
d-channel => 78
b-channel => 79-93

[span zt]
name => OpenZAP
number => 4
trunk_type => Z1
#trunk_type => E1
b-channel => 94-108
d-channel => 109
b-channel => 110-124

2. And then in error message of mod_openzap's loading it's possible to see dialect's index:

2008-09-19 16:12:48 [ERR] mod_openzap.c:1638 load_config() Error starting OpenZAP span 1 mode: 0 dialect: 0 error: Unknown trunk type!
2008-09-19 16:12:48 [ERR] mod_openzap.c:1638 load_config() Error starting OpenZAP span 2 mode: 0 dialect: 2 error: Unknown trunk type!
2008-09-19 16:12:48 [ERR] mod_openzap.c:1638 load_config() Error starting OpenZAP span 3 mode: 0 dialect: 4 error: Unknown trunk type!
2008-09-19 16:12:48 [ERR] mod_openzap.c:1638 load_config() Error starting OpenZAP span 4 mode: 0 dialect: 6 error: Unknown trunk type!

- this conforms to PRI configuration:

<configuration name="openzap.conf" description="OpenZAP Configuration">
  <settings>
    <param name="debug" value="1"/>
  </settings>
  <pri_spans>
    <span id="1"> 
      <param name="dialect" value="q931" />
      ...
    </span>
    <span id="2">
      <param name="dialect" value="national" />
      ...
    </span>
    <span id="3">
      <param name="dialect" value="dms"/>
      ...
    </span>
    <span id="4"> 
      <param name="dialect" value="5ess" />
      ...                                                                                                                                                                                      
    </span>                                                                                                                                                                                            
  </pri_spans>
</configuration>
                                                                                                                                                                                                                    
But if now to write unknown FreeSWITCH dialects into a PRI configuration,

    <span id="3">
      <param name="dialect" value="XYZ" />    
      ...
    </span>
    <span id="4"> 
      <param name="dialect" value="euro" />    
      ...                                                                                                                                                                                      
    </span>                                                                                                                                                                     
  </pri_spans>
</configuration>

- then we'll get such mistake message:

2008-09-19 16:25:44 [ERR] mod_openzap.c:1638 load_config() Error starting OpenZAP span 1 mode: 0 dialect: 0 error: Unknown trunk type!
2008-09-19 16:25:44 [ERR] mod_openzap.c:1638 load_config() Error starting OpenZAP span 2 mode: 0 dialect: 2 error: Unknown trunk type!
2008-09-19 16:25:44 [ERR] mod_openzap.c:1638 load_config() Error starting OpenZAP span 3 mode: 0 dialect: 2 error: Unknown trunk type!
2008-09-19 16:25:44 [ERR] mod_openzap.c:1638 load_config() Error starting OpenZAP span 4 mode: 0 dialect: 2 error: Unknown trunk type!


It's visible that:
1. FreeSWITCH doesn't identify dialects "euro" и "XYZ"...
2. Insted them it substitutes dialect "national" => 2 without any debug message.
