Grandstream Networks manual HT503 FXO Port Configuration

Figure 1-4: HT503 FXO Port Configuration

Below (Figure 1-4) is the FXO Port related configuration. Please configure only the mentioned parameters and do not change and leave all other parameters as default:

∙ Account Active: Yes

∙SIP User ID: Use any digits you want. HT503 just need some digits here to send to surveillance box therefore you can put ANY digits here. Here “110” is used as example.

∙ SIP Registration:NO

This is very important as there is NO SIP Server involved and we just manipulate the IP of each other device to make them work with each other.

∙Outgoing Call w/o Registration: YES

This is important also because NO SIP Server therefore no credentials involved here. The application is assumed in a secure and trusted LAN environment.

∙ Local SIP Port: 5062

This is the port HT503 FXO port will listen to.
