The setup is similar to PSTN, but uses mode: flow when mapping phone numbers. **** ![](https://api.archbee.com/api/optimize/SK2urIgCC2ml99YyqWOSl/K2sc4YfAy2tfPxKU4zVca_screenshot-2026-01-24-at-33347apm.png) **** **Setup Flow:** :::BlockQuote Create Trunk → 2. Map Phone Number (mode: flow) → 3. Map ACL to Trunk ::: ## StreamKit: Create Trunk 1\. Create Trunk Creates a new SIP trunk. This is the first step for all SIP Trunking use cases. A SIP Trunk acts as a virtual connection between your communication system (PBX/Contact Center) and Exotel's telephony network. ### HTTP Request :::BlockQuote POST https\://\:\@\/v2/accounts/\/trunks ::: ### Request Headers | Header | Value | | ------------ | ---------------- | | Content-Type | application/json | ### Request Parameters The following parameters are sent as JSON in the body of the request: | Parameter Name | Mandatory/Optional | Value | | -------------- | ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------- | | trunk\_name | Mandatory | String; Unique identifier for the trunk. Must be alphanumeric with underscores only, maximum 16 characters. Example: outbound\_trunk, my\_pbx\_trunk | | nso\_code | Mandatory | String; Network Service Operator code. Use ANY-ANYfor standard configuration. | | domain\_name | Mandatory | String; SIP domain for the trunk. Format: \.pstn.exotel.com. Example: ameyo5m.pstn.exotel.com | ### Example Request :::BlockQuote curl -X POST "https\://\:\@\/v2/accounts/\/trunks" \\ -H "Content-Type: application/json" \\ -d '\{ "trunk\_name": "outbound\_trunk", "nso\_code": "ANY-ANY", "domain\_name": "\.pstn.exotel.com" }' ::: ### HTTP Response On success, the HTTP response status code will be 200 OK. The trunk\_sidis the unique identifier of the trunk - **save this value** as it will be required for all subsequent API calls. ### Example Response :::BlockQuote \{ "request\_id": "10a67da360d446378d5c2b66407b7f18", "method": "POST", "http\_code": 200, "response": \{ "code": 200, "error\_data": null, "status": "success", "data": \{ "trunk\_name": "outbound\_trunk", "date\_created": "2026-01-23T09:24:59Z", "date\_updated": "2026-01-23T09:24:59Z", "trunk\_sid": "trmum1f708622631150902801a1n", "status": "active", "domain\_name": "ameyo5m.pstn.exotel.com", "auth\_type": "IP-WHITELIST", "registration\_enabled": "disabled", "edge\_preference": "auto", "nso\_code": "ANY-ANY", "secure\_trunking": "disabled", "destination\_uris": "/v2/accounts/ameyo5m/trunks/trmum1f708622631150902801a1n/destination-uris", "whitelisted\_ips": "/v2/accounts/ameyo5m/trunks/trmum1f708622631150902801a1n/whitelisted-ips", "credentials": "/v2/accounts/ameyo5m/trunks/trmum1f708622631150902801a1n/credentials", "phone\_numbers": "/v2/accounts/ameyo5m/trunks/trmum1f708622631150902801a1n/phone-numbers" } } } ::: ### Response Parameters | Parameter Name | Type & Value | | --------------------- | ---------------------------------------------------------------------------------------------------------------------------------- | | request\_id | String; Unique identifier for this API request | | method | String; HTTP method used (POST) | | http\_code | Integer; HTTP status code (200 for success) | | trunk\_sid | String; **Important** - Unique identifier for the trunk. Save this for subsequent API calls. Example: trmum1f708622631150902801a1n | | trunk\_name | String; Name of the trunk as provided in request | | domain\_name | String; SIP domain for the trunk | | status | String; Current trunk status: active- Trunk is ready for use, inactive- Trunk is disabled | | auth\_type | String; Authentication type. Currently only IP-WHITELISTis supported | | registration\_enabled | String; SIP registration status: enabledor disabled | | edge\_preference | String; Edge server preference. Default: auto | | nso\_code | String; Network Service Operator code | | secure\_trunking | String; TLS status: enabledor disabled | | destination\_uris | String; API path to manage destination URIs for this trunk | | whitelisted\_ips | String; API path to manage ACLs (whitelisted IPs) for this trunk | | credentials | String; API path to credentials for this trunk | | phone\_numbers | String; API path to manage phone numbers for this trunk | | date\_created | String; ISO 8601 timestamp when trunk was created | | date\_updated | String; ISO 8601 timestamp when trunk was last updated | ## StreamKit: Map Phone Number (Flow Mode) Same endpoint as PSTN, but with mode: flowto route calls to Voice AI bot. ### Example Request :::BlockQuote curl -X POST "https\://\:\@\/v2/accounts/\/trunks/\/phone-numbers" \\ -H "Content-Type: application/json" \\ -d '\{ "phone\_number": "+919876543210", "mode": "flow" }' ::: ### Example Response :::BlockQuote \{ "request\_id": "9351dabddc21476e8351d662f1ce31e1", "method": "POST", "http\_code": 200, "response": \{ "code": 200, "error\_data": null, "status": "success", "data": \{ "id": "41523", "phone\_number": "+919876543210", "trunk\_sid": "trmum1f708622631150902801a1n", "date\_created": "2026-01-23T13:28:11Z", "date\_updated": "2026-01-23T13:28:11Z", "mode": "flow" } } } ::: ## StreamKit: Map ACL to Trunk Registers your server's public IP address for authentication. This is required for **Outbound/Termination** calls - allowing your system to send calls through the trunk. ACL (Access Control List) ensures only authorized IP addresses can use your trunk for outbound calling. ### HTTP Request :::BlockQuote POST https\://\:\@\/v2/accounts/\/trunks/\/whitelisted-ips ::: ### Request Headers | Header | Value | | ------------ | ---------------- | | Content-Type | application/json | ### Request Parameters | Parameter Name | Mandatory/Optional | Value | | -------------- | ------------------ | ---------------------------------------------------------------------------------------------------------------------- | | ip | Mandatory | String; Your server's public IP address. Must be a valid IPv4 address. Example: 44.248.146.11, 203.0.113.50 | | mask | Optional | Integer; Subnet mask in CIDR notation. Default: 32(single IP). Use 24for /24 subnet, 16for /16 subnet. Example: 32, 24 | ### Example Request :::BlockQuote curl -X POST "https\://\:\@\/v2/accounts/\/trunks/\/whitelisted-ips" \\ -H "Content-Type: application/json" \\ -d '\{ "ip": "44.248.146.11", "mask": 32 }' ::: ### HTTP Response On success, the HTTP response status code will be 200 OK. ### Example Response :::BlockQuote \{ "request\_id": "3daaed4cd05d443f854e07e60dd4c008", "method": "POST", "http\_code": 200, "response": \{ "code": 200, "error\_data": null, "status": "success", "data": \{ "id": "1153", "mask": 32, "trunk\_sid": "trmum1f708622631150902801a1n", "ip": "44.248.146.11", "friendly\_name": null, "date\_created": "2026-01-23T11:37:36Z", "date\_updated": "2026-01-23T11:37:36Z" } } } ::: ### Response Parameters | Parameter Name | Type & Value | | -------------- | ----------------------------------------------------------- | | id | String; Unique identifier for this ACL entry.
