  1. No audio on Hold or 3 person call

    aws2p, when I updated 3CX complain about Server 2008 R2 just for IOs phones, but I don't have any of theses. The problem is not OBi since I also have a Grandstream Gateway and have the same issue. Please remember that I can't hear HOLD song when put a call on hold too, so the problem start...
  2. No audio on Hold or 3 person call

    Hi. I am having an issue when trying to add a 3 person to the call. I try that by adding these person using the Windows Phone or by analog phone (Flash dial 3 person, presh flash again to conect all). The person is connected but after that no one can hear anyone. I remember this was working...
  3. 3CX 16, SIP trunk fail to register

    @leejor I can't use DD-WRT here, but I use it on my remote house on the beach, to connect to this house by PPTP VPN. I know well DD-WRT and already have some suggestions accepted by the firmware developer : - ). @Trestill I agree, but my adsl router don't have a option to redirect PPTP ports...
  4. 3CX 16, SIP trunk fail to register

    No problem this time! The problem is really the adsl router. After the ISP provider force the new IP as you can see the VoIP SIP Trunk is registered successfully. Now the big problem is to convince my ISP provider to fix they firmware from the other adsl modem.
  5. 3CX 16, SIP trunk fail to register

    @Lee Cramman yes, I am using a fixed internal IP on the 3CX Server, the router has an DMZ rule to this server IP. On 3CX Server I am using Type of Authentication: Register/Account based.
  6. 3CX 16, SIP trunk fail to register

    Hi @leejor, what a long time I don't talk to you. My ISP provider use the router from Pace V5471-002. They change the original firmware and build their own. Every time the router is rebooted they assign a new IP, and also they force [because they are crazy] a new IP after 48 hours of...
  7. Solved 3CX Provisioning file - change ip

    Thank you all. I remember that is possible to select all extensions and click on Edit so it apply to all : - )
  8. 3CX 16, SIP trunk fail to register

    @YiannisH_3CX And there is a way to fix that? Force something on 3CX maybe? (Maybe one of these options? *Put Public IP in SIP VIA Header *Force Invites to be sent to IP of Registrar *Select which IP to use in 'Contact' (SIP) and 'Connection'(SDP) fields) @bkreeger There is nothing on IP...
  9. 3CX 16, SIP trunk fail to register

    Yep, already using it. And please note that I am using server ip, not fqdn. Still dont know the problem here.
  10. Solved 3CX Provisioning file - change ip

    No way to change it globally? Instead of change that on every extension?
  11. Solved 3CX Provisioning file - change ip

    Hi, my 3CX server is sending the external interface ip instead of local interface ip on the provisioning file. I just update from 3CX v14 to v16. How can I change these lines: <PBXLocalAddr>192.168.25.254</PBXLocalAddr>...
  12. 3CX 16, SIP trunk fail to register

    Hi. I am having some issue with SIP TRUNK registration. I am using IP to register my SIP TRUNK, but, every time my ISP changes my IP address I cant register until turn off and on my isp router. Until do that, I receive the following message: Registration at Voipmundo has failed. Destination...
  13. 3CX and SIP PROXY (DD-WRT)

    I understand, make total sense. I was testing without milkfish already. I also try with SBC, without SBC, directly, but as you say, probably i need to live with that. For testing purpose I will still test another gateway directly too.
  14. 3CX and SIP PROXY (DD-WRT)

    Leejor, only when using the gateway. If I call from one extension to another extension, the audio ramain local only.
  15. 3CX and SIP PROXY (DD-WRT)

    Exactly, thats the reason why I believe that just unchecking "PBX Delivers Audio" should fix that issue. Thtat's not a problem, all IPs can reach each other without problem and there is no firewall. I was trying it right now (see my questions here: http://www.3cx.com/blog/docs/session-bo ...
  16. 3CX and SIP PROXY (DD-WRT)

    But even without using milkfish, the audio stream should not stay local if I uncheck "PBX Delivers Audio" under extensions and Gateway? Because for call between ATAs, even without milkfish the audio stay local. So I try mikfish, thinking that may fix the local audio for the gateway, but as you...
  17. 3CX and SIP PROXY (DD-WRT)

    What I am trying to do here is to keep audio between remote ATA and Gateway local. At the beach house I have two ATAs and one PSTN Gateway. If I call from one ATA to another there is no VPN trafic (just SIP messages go trough the tunnel). Now, when I call from one ATA using the local gateway...
  18. 3CX and SIP PROXY (DD-WRT)

    I fix the problem by enabling one option on SIP PROXY called "From-Substitution" and on the field "From-Domain" I type the same FQDN name I have under Settings -> Network -> FQDN -> Local SIP domain (See attached file). But, after that I can't use the gateway to receive calls, only to make...
  19. Call Quality Issues with 3CX SBC

    Michael, if the remote place has one ATA and one PSTN Gateway. If the ATA make some call using the local PSTN gateway the audio will stay local? Thanks.
  20. 3CX and SIP PROXY (DD-WRT)

    Well... Apparently, it work if I change under Settings -> Network -> FQDN -> Local SIP domain -> 10.1.1.18 (the IP from SIP PROXY)... But, I need to use my NO-IP alias here, other way the tunnel will not work for Android Phones. So, what I need to do do both of then work? How can I add more...
