Hi ewtto,

Do you mean a user on 4G network can not send SIP-REGISTER to Brekeke SIP Server?

Which SIP client product is this user using?

Thanks

I used Grandstream UCM 61XX series. I now have a problem. I want to do forwarded by registered Brekeke SIP SERVER. So my other mobile users can properly registered.
BREKEKE first to register, and then forwarded to the UCM.

thanks

Do you want to forward a call to Grandstream UCM 61XX from a mobile user?

What SIP client is a mobile user using?

Have you read this?

I now need to address the problem is to move the end can not be registered and the normal call.

I would like to do a registration and forwarding RTP by BREKEKE. Let me mobile to register and end the call.

Do you have the same problem even if you use a SIP client at wifi?

I also have a similar problem on 4G call connection though it works on wifi well.

- Registration is done successfully
- Invitation call is not recognized from a callee, so status stays on 'Inviting'

Is there any other setting required for 4G

Choi,
Which version of Brekeke SIP Server are u using?

Is the callee using an IP address in Shared Address Space?
https://tools.ietf.org/rfc/rfc6598.txt
It is 100.64.0.0-100.127.255.255.

Which SIP client is the callee using?

Brekeke SIP server version is 3.5.3.0.

From my understanding, Brekeke SIP server supports Shared address space from 3.4 so I guess no need to setup something for RFC6598 on Brekeke SIP Server.

Could you let me know how callee uses IP in Shared address space? Or do I need to set up the configuration on a server itself or Brekeke Server or Client(PortSIP)?

If the client is registered in the Brekeke SIP Server, you can check the client's source IP address in [Registered Clients] page. See " (Source IP Address) " in the page.


Try reducing NAT traversal's [Interval (ms)] in [Configuration]->[SIP] page. such as 5000. It will keep opening the connection pass between the SIP Server and the client.
