      Hi all
      I hope that someone could help me.
      Env.:
      PFSense 2.4.2 without additional packages. 1 Yealink W52P in LAN 1. The VOIP telephone connect to a swiss sip Provider outside of the pfsense to port 5060.
      The Registration failed. If I sniff, I see, that the phone makes a dns query and receive the correct IP. May it couldn't connect to the Provider.

      Checks:

      • I've tested with an other SIP phone, same
      • Sipproxy (only Change the outbound/inbound Interface), set outboundproxy in the sipphone to the pfsense gw ip, same

      Has anyone an idea?

        Step 1: Uninstall siproxd. It will almost certainly only hurt, not help.

        Step 2: What else is in the capture after the phone obtains the IP address to connect to?

        DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

          Not related to pfSense yet.
          Remove all your customization - Sipproxy, outboundproxy, etc., then speak to your provider.
          If you want to find a root cause yourself - look into your SIP traffic on both LAN and WAN.

            Helo all
            I've found the Problem. It wasn't on the pfsense.
            It was a DOS-Prevention on a Zyxel Switch.
