No matter what I put in for outbound caller id it always shows up as private or unknown. We are using SIPSTATION trunks with the SIPSTATION module. Running FreePBX version 2.9. I have contacted them and they say it is because I am not populating the outbound CID field in the extensions but I am. it just does not work. I have also tried the trunk CID option too. Still no go. anyone have any ideas? Maybe a firewall issue???
note: SIPATATION says they are getting “unknown” in the CID field from the PBX.
