    Or you'll walk over you your Smart Fridge for a late night beer and a male voice will calmly say "I'm sorry, Bob. I can't let you do that."

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    Thank you folks. I am already set up woth GoTrunk for £5.99 inc VAT and have the PBX, handset and intercom (we have a disabled occupant). The copper landline is gone now as an added bonus.

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    I do appreciate the suggestions and you were correct - the router was doing its job properly once I got the SIP ALG settings correct. I am happy to report that GoTrunk (Trunk Provider) were able to help with understanding the pcap traces, folks here gave me enough guidance that I could...

    A shame it isn't that cheap over here in the UK. Mind you we have the 20% tax applied to everything first.

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    I was hoping to minimise my monthly outgoings by just paying for the SIP trunk and purchasing my own PBX as I am an unpaid carer. Renting a cloud PBX does add a little extra to the monthly cost.

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    UPDATE : Sorted... almost. GoTrunk were able to assist me with the "Unauthorized" error. In one of the older Guides I had followed it had advised me to turn on "Auth Trunk" in the Trunk Settings... "If enabled the UCM will send a 401 response to the incoming call to authenticate the Trunk"...

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    Here is a comment from GoTrunk about my issue with incoming calls and UDP port 5060. Is it possible I have the either the firewall or the PBX set up incorrectly when registering the UDP ports?

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    When I look at the GoTrunk SIP Trunk CDR it does appear to give me full visibility of the SIP frames and their contents. This is helpful because I can see the incoming request to my WAN and I can see the response of Unauthorized. I have colour coded the relevant parts of the failed Inbound call...

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    I also don't seem to be supplying CallerID on outbound calls which is a pain. There are fields for it in the Grandstream PBX for the Trunk, Outbound route and also Extension level but they don't explain the hierarchy nor the expected format (01234... or +441234...). Any clues?

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    I wish they had said how though. Right... some progress. I have set SIP Passthrough and RTSP Passthrough to Enable and powered all the equipment off and on. I can make an outgoing call but CallerID is not being provided in the correct format. That will be an issue with my Extension or Outbound...

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    I just found the 2020 explanation where the Disabled / Enabled / Enabled + NAT Helper were explained which makes a lot of the older SIP guides that say "disable SIP ALG" out of date. What do you advise for the RTSP Passthrough then?

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    Thank you for the great replies. I do have an assigned LAN IP address for the GrandStream PBX in the router and I think the Port Forwarding is correct as per this page... https://gotrunk.com/docs/networkconfiguration/ The part I am unsure if I am doing correctly is where they mention... "The...

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    Sadly no change in my issue and in attempting to "fix" it I have made it worse. Now I get no incoming calls at all. Would folks mind having a think about what I should check to get this working again please? As I mentioned above, I have a Dynamic IP from my ISP, the Asus router with Merlin, an...

    I will give that a go and see if it helps, thanks.

    [AX86U] Half audio on incoming VoIP SIP calls, NAT mismatch?

    I am having an intermittent issue with only half the audio being present on incoming VoIP calls to my PBX and the VoIP provider is wondering if it is a NAT Mismatch at the ASUS router. I wonder if you could give your opinion on the issue please? Here is the equipment being used... Router ...
