VOIP on ATP200
Freshman Member
Testing VOIP access from behind an ATP200 and I get the following error:
Voip Tester failed to make a SIP call.
Check the following:
- External firwall may need to allow the SIP and RTP ports
- Disable router SIP ALG
What do I need to adjust to get this to work? I've made no known changes to SIP from factory defaults. This has the latest 5.02 firmware, if that makes any difference. I checked the ALG section and Enable SIP ALG is NOT checked.

Sorry, but I found out that this was a misconfiguration on the VOIP test, not the firewall. This is resolved.1

Hi @BMS,Can you post a brief network topology with caller, callee, and sip server marked, it would be helpful to understand about call flow.
