Hi Larry and Imoore,

yes, looking at the txt files it makes sense. First call ist 401, 2nd gives the 200 ok.

I set up a remote log server now and activated the remote syslog in the n670. Another result. We can see the call start:

I shortend the lines a bit. According to the rsyslog the udp package size is to large. Do I have the possibility to limit the udp package size in Opnsense?

@Larry, also thanks a lot ...

Hi lmoore, thanks a lot. Just only noticed the screenshots. Yesterday I went through the first document you linked. This is interesting. Under Sip security chapter 5.4 we read about error 401 (unauthorized). Yesterday I installed zeek on my opnsense which writes a sip.log. When I dial a number I get error 401.

For me this confirms now at least that it's not opnsense which blocks the connection. Will have to look at the document more closely and see if I understand all this.
I'll compare your screenshots with my settings. Maybe this changes the behavior of the registration process.
Thanks again for your help.

Hello Olmo,

thanks for the reply. IPv6 is not supported by the device according to the web configurator. FW rules including outbound are already set. I used the same setup with the Fritzbox which worked. I simply exchanged the devices. That's why I don't understand what's going on. Anyway, I'll recheck the firewall rules.

Hello Imoore,

yes, I already have downloaded the manuals for the N670. I read about the remote syslog server. Maybe I should try this as you suggest it. As said above firewall rules are set up and logging is enabled. The firewall doesn't show any blocks. I checked it with the live view while dialing.
Your second link looks interesting. I'll go through it. Thanks a lot for that.
I'll report back.

Thanks again to both of you.

Hello all,

I've following setup at home:

Internet --> Opnsense --> Unify switch --> N670IP Pro

As handset I use Gigaset S700H Pro.
My ISP is Vodafone (Cable) in Baden-Wuerttemberg. Prior to this setup I used the Fritzbox 6660 Cable as phonebox which worked properly without any troubles. Since I wanted to get rid of the Fritzbox I acquired the VoIP Box N670. I've configured it with all required data and I get the Box registered via SIP at the Vodafone server. Incoming calls are possible. Outgoing not. As soon as I dial a number on the handset the connection is immediately aborted and the display shows "not reachable". I searched a lot for any solutions or reasons why this happens. Couldn't find any more information. Even the firewall logs don't show any blocks.
Does anyone have an idea what could cause this issue?
Thanks already in advance.
