SfB - Can not accept call when outside of office RRS feed

  • Question

  • Hi Guys.

    If i am doing homeoffice i am not able to accept calls to my SIP Phonenumber. It is not possible for me to accept incoming calls from Internal Clients and not from numbers from outside.

    I get the message to accept the call and i can click on it but it will not open the call...

    on Caller-side it seems to ring still.

    What i found out is that i can DO CALLS but i can not accept calls.

    the same thing for Messages....if someone wants to message me he got the message that the message was not send, but i got the message with a delaay of couple of seconds/minutes.

    We checked all Ports from the SfB List. All ports are correct.

    All Functions works well if i am in the OFFICE if i am outside the office i can only START CALLS but i can not ACCEPT calls.

  • Do you use a VPN to connect to your office or without vpn?

    You should check your Edge configuration, it looks like a problem with the communication to your Edge server from external. Maybe firewall/routing problem?

  • Off course it should work without vpn.

    Looks like something on your Edge configuration is wrong. You can check a little bit mor with the remote analyzer tool

  • Ok, please check you Edge server for audio/video connection or analyze you client log for this error for further troubleshooting.

    here is a good link for general troubleshooting

  • OK We opened the Firewall completly for the EDGE but the problem is still happening so there is no issue with the firewall or the NAT but its a CONFIGURATION ISSUE...any idea?
