Hi, I'm an engineer but new to OBi and VoIP. I have a line set up through my OBi200 and Flowroute. Incoming calls work perfectly. Outgoing calls to some numbers (like my cell phone) work fine but for others, if someone picks up, they report picking up and nothing happening and I don't hear their voice or voicemail.

Am I missing something? Nothing seems out of the ordinary in call records in Flowroute but there isn't a lot of detail.

Any help would be much appreciated!

You can get some real-time info from your Obi while a call is in progress.

If you don't already know the IP address on your LAN of the OBi, dial ***1 and it will be read out to you.

Put that in a browser and log in with user admin and password admin.  (Unless you changed the password.)

Click on Status and then on Call Status. IIRC the page will not update automatically.  You need to refresh manually.

Screenshot of example call status attached

I have configured my router with static outbound NAT for the OBi200 and configured port forwarding in accordance with OBi (https://www.obitalk.com/info/faq/Troubleshooting-sec/ports-to-keep-open-on-my-router) and Flowroute (https://support.flowroute.com/customer/portal/articles/1852958-set-firewall-policies-for-flowroute-s-direct-audio) recommendations

I figured it out! The instructions I was using (https://docs.netgate.com/pfsense/en/latest/nat/configuring-nat-for-a-voip-pbx.html) indicated that I should filter incoming traffic for the port forward by known SIP Trunks but I noticed that in the call status, the "Peer RTP Address" was not in any of those ranges. A post on another forum mentioned that Flowroute hands off, rather than proxying, connections once established as a measure in improve call quality. In any case, allowing ALL incoming traffic to RTP ports to be forwarded to the PBX instead of just traffic from known Flowroute SIP Trunks fixed the issue for a known bad phone number.

It is very rarely necessary to do any configuration of ports on a home router to work OK with an OBi.

Note that all but one of the ports listed in that Obihai FAQ are outgoing and are to be open.  I have had hands-on experience with tens of home routers and not a single one running stock firmware had any means for end-users to control opening and closing of outgoing ports.  Yes, most had user controls for port forwarding but that is on inbound trafffic.

The one incoming port mentioned in that FAQ is 10000.  That is used by Obitalk, not GV nor any of the usual SIP ITSPs.
