RingCentral Trunking with Incredible PBX

Here’s how a RingCentral chan_sip Trunk in FreePBX should be set up assuming 15551234567 was your assigned DID:

username=15551234567
fromuser=15551234567
defaultuser=15551234567
type=peer
secret=your-password
host=sip.ringcentral.com
fromdomain=sip.ringcentral.com
insecure=port,invite
dtmfmode=rfc2833
disallow=all
allow=ulaw&alaw
context=from-trunk

Registration String: 15551234567:yourpassword@sip10.ringcentral.com:5090/15551234567

The Outbound Route to process RingCentral calls should include a CallerID Number that is purchased from RingCentral. For U.S./Canada 10-digit calling, the Prepend, Prefix, Dial Patterns should be as follows: 1,leave-blank,NXXNXXXXXX.

The Inbound Route to process incoming calls from RingCentral should specify your 11-digit DID and assign the incoming call destination desired.
