I looked in mod_openzap.c and I didn't see any references to channel variables. However, you have context and dialplan options. I suggest that you create a dialplan context just for your FXS port(s). Try this. Create conf/dialplan/fxs-ports.xml:

<include>
  <context name="fxs-ports">
    <extension name="outbound">
      <condition field="destination_number" expression="^(.*)$">
        <action application="set" data="toll_allow=local,domestic,international"/>
        <action application="transfer" data="$1 XML default"/>
      </condition>
    </extension>
  </context>
</include>

Then in your openzap.conf.xml change the context for the analog span(s) with the FXS ports:
<param name="context" value="default"/>

Restart FS after making these changes and then give it a shot. You should see the call from the analog phone going into context "fxs-ports" and then get transferred over to the default context where it will act like your SIP phones because we manually set the ${toll_allow} chan var.

Hi, Michael,

I have multiple sip phone that are working fine.  When I dial a 10 digit
number they connect with my sip provider and place the call.  The
openzap configured phone gets dial tone and can call other extensions,
however when I dial a 10 digit number it gives me a busy.  In the log I
see it appears to be failing on the toll_allow test:

Dialplan: OpenZAP/1:1/7707190068 parsing [default->local_call]
continue=false
Dialplan: OpenZAP/1:1/7707190068 Regex (FAIL) [local_call]
${toll_allow}() =~ /local/ break=on-false
Dialplan: OpenZAP/1:1/7707190068 parsing [default->domestic_call]
continue=false
Dialplan: OpenZAP/1:1/7707190068 Regex (FAIL) [domestic_call]
${toll_allow}() =~ /domestic/ break=on-false
Dialplan: OpenZAP/1:1/7707190068 parsing
[default->international.example.com] continue=false
Dialplan: OpenZAP/1:1/7707190068 Regex (FAIL)
[international.example.com] ${toll_allow}() =~ /international/
break=on-false

This is the area when it should be placing the call, I belive.  When
placing a call from a sip phone I see:

Dialplan: sofia/internal/1003@192.168.2.51 parsing [default->local_call]
continue=false
Dialplan: sofia/internal/1003@192.168.2.51 Regex (PASS) [local_call]
${toll_allow}(domestic,international,local) =~ /local/ break=on-false
Dialplan: sofia/internal/1003@192.168.2.51 Regex (PASS) [local_call]
destination_number(7707190068) =~ /^(\d{10})$/ break=on-false
Dialplan: sofia/internal/1003@192.168.2.51 Action
set(effective_caller_id_number=${outbound_caller_id_number})
Dialplan: sofia/internal/1003@192.168.2.51 Action
set(effective_caller_id_name=${outbound_caller_id_name})
Dialplan: sofia/internal/1003@192.168.2.51 Action
set(continue_on_fail=true)
Dialplan: sofia/internal/1003@192.168.2.51 Action
bridge(sofia/gateway/${default_gateway}/7707190068)

I simply want this extension to be able to dial out.  The configuration
is 99% default.

Thanks,
Jim.
