3. IP to Port
In this section, we introduce how to achieve making outbound calls from UCM6102 through PSTN line on TA810.
Step 1. Create one outbound route on UCM6102.
Path: PBX→Basic/Call Routes→Outbound routes→Create New Outbound Rules
Choose the SIP trunk “TA810” which is connecting to Yeastar TA810. Set the dial rule, here we set Pattern as “_9.” and Strip 1 digit, meaning that you have to dial digit 9 before the destination number.
Step 2. Configure one “IP ->port” Route on TA810.
Path: Gateway→Routes Settings→”IP->Port” Suppose that you want to use PSTN FXO1 to call out.
Route Name: give a name for the route, “UCM”.
Call Source: choose the VoIP trunk which is connected to UCM, “SPS—CUM”.
Call Destination: choose “Port—FXO1”.
Step 2. Test a call from UCM6102
Now, you can make external calls from UCM6102 through the PSTN 1 on TA810. As the dial rule set on UCM outbound route, you need to dial 9 before the number. For example, if you want to call number 45672421, you need dial 945672421 on your phone.
4.Port to IP
In this section, Introduce how to route incoming calls from PSTN line to UCM6102.
Step 1. Create an inbound route on UCM.
Path: PBX→Basic/Call Routes→Inbound routes→Create New Inbound Rules
Here we configure the inbound route as below:
DID Number: 123456
Destination: Extension 1000
The incoming calls with DID number 123456 would be routed to extension 1000.
Step 2. Configure one “Port->IP” Route on TA.
Path: Gateway→Routes Settings→”Port->IP”
Route Name: give a name for the route, “UCM”
Call Source: choose the Port1-FXO1
Call Destination: choose the VoIP trunk which is connected to UCM, “SPS—UCM”.
Hotline: set Hotline to 123456, which is the same number with the DID number set on UCM Inbound route.
Step 3. Test a call.
Dial the PSTN’s number(1625351623) on your mobile phone, the call will be routed to UCM extension1000.
