How to Set Synway PBX Inbound, Outbound?
Step 1
We log in to the interface of our Synway switchboard.
We click on PBX > Trunk > Add.
Step 2
We write the IP address of the switchboard on the other side into the Trunk IP/Domain section.
We choose which interface to trunk from the ETH port section.
After these procedures, we have installed the IP to IP trunk. 
Step 3
The SIP port to be used for trunking is entered in the PBX>SIP SETTINGS>TRUNK PROFILE SETTING section.
We come to the inbound route section to receive incoming calls. Here we select the trunk we configured.
In the did pattern section, we write the ^\d*$ rule, which is the synway general incoming call rule.
The target number of the incoming call is defined in the *DID Number section.
In our Synway outbound settings, we can write the general search rule ^\d*$.
We can perform operations such as deleting and adding from the end and beginning of the number from the strip, prepend and suffix sections.
