How to configure calls to SIP URIs on other SIP servers

[fvgjseduegvhiu]

Hello all,
I am trying to configure FusionPBX to allow me to call users of other SIP servers by SIP URI, such as "12345@example.com". I currently have it set to allow a modified URI, replacing "@" with "-at-", and when using this format my server connects the call. However, when I replace "-at-" with "@" in the dialplan and try to call the corresponding URI, I am given a "forbidden" message, and the logs on FusionPBX state that I must setup the domain I am trying to call as a Domain on my server, and add the extension to my directory under that domain. The server seems to think I want to call myself for some reason. I cannot for the life of me figure out what I'm doing wrong. I am attaching my working dialplan below, the non-working one is the exact same except for replacing "-at-" with "@". Thank you!
<extension name="outbound-uri" continue="false" uuid="00fc9888-d5a2-4193-a406-ca38b0aa9bf6"> <condition field="destination_number" expression="^([0-9a-zA-Z]+)-at-(.+\..+)$"> <action application="bridge" data="sofia/external/$1@$2"/> </condition> </extension>

I've added the sip uri dialplan from the freeswitch vanilla configs after the VM dialplan

<extension name="external_sip_uri" continue="true" uuid="07e235a2-5638-42ea-a447-05442cc56aa7">
    <condition field="source" expression="mod_sofia"/>
    <condition field="${outside_call}" expression="^$"/>
    <condition field="${domain_exists(${sip_req_host})}" expression="true">
        <anti-action application="bridge" data="sofia/${use_profile}/${sip_to_uri}"/>
    </condition>
</extension>

It doesn't give me the "must setup a domain" error any longer but I've not been able to actually connect with any sip uris. It may be the ones I've tried aren't active any longer, I tried using the ones on nerdvittles for weather, news, etc.

I'll try this dialplan in a bit, thank you. If you're looking for a testing URI, I'd try 4444@sip2sip.info which is just an echo.

I have a dialplan using that uri i just didn't think about it. For some reason the above doesn't work even though I have a test dialplan that performs the same actions just more directly. I copied the freeswitch conference dialplan and just changed destination to the 4444 uri and that works. If you figure out the issue I'd like to know as well please
