FreeSWITCH 1.10.10 Simple graphical interface 7-Record a problem when configuring the gateway

0. Question

The user is using Xunshi HX4E. After configuring according to this article, you can make outgoing calls but cannot make incoming calls.

1. Investigation

1. The direct call to the gateway hangs up, and FreeSWITCH does not receive any incoming message;
2. The gateway SIP log prompts itself 486 busy;
3. The packet capture revealed that the gateway sent the invite request to the correct IP address, but the message was sent to the gateway itself, which was quite puzzling;

After struggling for two hours, the user discovered that the network cable was connected to the PC port. It stands to reason that if the network port is bridged, there should be no problem with the network; if it is in routing mode, outgoing calls should not work either. Wondered. Why! ! ! ! ! ! . I checkedthe message manual and didn’t understand it.

After plugging it into the WAN port, there was no problem at all. It was a long day of experience.
