Connect Applet setup for inbound SIP
Route PSTN calls that hit your Exophone into your SIP trunk.
PSTN → Exotel DID → App Bazaar Flow (Connect) → sip:<trunk_sid> → Destination URI → Your SIP
Prerequisites
- Trunk created with destination URI set — Quickstart steps 1–4
- Phone number mapped to the trunk with mode
pstn - Destination reachable (firewall allowlist complete)
Configure the flow
- Open App Bazaar (use your regional dashboard)
- Create a new flow
- Add a Connect applet
- In Dial Whom, enter:
sip:<trunk_sid> - Save the flow
Map the DID
- Open Exophone / Numbers manager
- Select your DID
- Assign the Voice URL / flow to the flow created above
Verify
- Call the Exophone from a mobile
- Confirm INVITE arrives at your SIP URI
- Confirm two-way audio (UDP 10000–40000 open)
Dynamic Connect URL (optional)
For runtime routing, use a programmable Connect URL that returns JSON such as:
{
"fetch_after_attempt": false,
"destination": { "trunk": "trunk-2134" },
"custom_params": "param1=value1¶m2=value2",
"record": true,
"recording_channels": "dual"
}
