Hi, I am getting error ‘Call country not supported: PE’. I have enabled Inbound, but I need you to enable OUTBOUND calls to Peru (+51) for my account manually. I have already paid my invoice. ---

* * * For outbound calls to Peru, the approach depends on whether you’re using Retell-purchased numbers or imported numbers through custom telephony. **Retell-purchased numbers** support calling to 15 countries[(1)](https://docs.retellai.com/deploy/outbound-call). International calling restrictions apply based on this list[(1)](https://docs.retellai.com/deploy/outbound-call). **Imported numbers** through custom telephony (SIP trunking) have international calling that depends on your telephony provider’s settings[(1)](https://docs.retellai.com/deploy/outbound-call). If you’re using custom telephony with providers like Twilio, you need to configure geographic permissions. Search “geo” to find the “Voice Geographic Permissions” setting[(2)](https://community.retellai.com/t/problem-with-outbounding-call/514). Choose “Elastic Sip Trunking” in the selector and select the countries you would like to dial[(2)](https://community.retellai.com/t/problem-with-outbounding-call/514). You can also configure allowed outbound countries for your phone numbers. Navigate to **Phone Numbers** in your Retell dashboard, click on the phone number you want to configure, and under **Allowed Outbound Countries** , add the countries this number should be allowed to call[(3)](https://docs.retellai.com/reliability/fraud-protection). Changes are saved automatically[(3)](https://docs.retellai.com/reliability/fraud-protection). Via API, you can configure this using the Update Phone Number API with ISO 3166-1 alpha-2 country codes (e.g., “PE” for Peru)[(3)](https://docs.retellai.com/reliability/fraud-protection): ```bash curl -X PATCH "https://api.retellai.com/update-phone-number/+14155551234" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "allowed_outbound_country_list": ["US", "PE"] }' ``` [(3)](https://docs.retellai.com/reliability/fraud-protection) I don’t have information about manual account-level enablement for specific countries.

Hello @soporte If you are using a retell number, then it’s not allowed to call Peru You can check the allowed countries from here: [International Calling and Fees - Retell AI](https://docs.retellai.com/deploy/international-call#international-calling-and-fees) What you can do is to buy a phone number from any provider that supports Peru and connect it using SIP trunking. ---

To enable calling to countries not supported by Retell-purchased numbers, you can use Elastic SIP Trunking to connect your own phone number from a telephony provider that supports your target country[(1)](https://docs.retellai.com/deploy/custom-telephony). **Setting Up SIP Trunking for International Calls:** **Step 1: Create Elastic SIP Trunking with Your Provider** Set up a SIP trunk with a provider like Twilio, Telnyx, or Vonage[(1)](https://docs.retellai.com/deploy/custom-telephony)[(2)](https://docs.retellai.com/deploy/twilio)[(3)](https://docs.retellai.com/deploy/telnyx). Configure both termination (outbound) and origination (inbound) settings[(1)](https://docs.retellai.com/deploy/custom-telephony)[(2)](https://docs.retellai.com/deploy/twilio)[(3)](https://docs.retellai.com/deploy/telnyx): - For termination, note your provider’s termination SIP URI[(2)](https://docs.retellai.com/deploy/twilio)[(3)](https://docs.retellai.com/deploy/telnyx) - For origination, set Retell’s SIP server address as: `sip:sip.retellai.com`[(1)](https://docs.retellai.com/deploy/custom-telephony) - Configure authentication via IP whitelisting or credentials[(2)](https://docs.retellai.com/deploy/twilio) **Step 2: Enable International Dialing in Your Provider** For providers like Twilio, search “geo” to find the “Voice Geographic Permissions” setting and select the countries you want to dial[(2)](https://docs.retellai.com/deploy/twilio)[(4)](https://community.retellai.com/t/enable-israel-972-for-outbound-calls-on-my-account/781). Choose “Elastic SIP Trunking” in the selector and enable your target countries[(2)](https://docs.retellai.com/deploy/twilio). **Step 3: Import Your Number to Retell** Import your number to Retell via the dashboard or API, providing[(1)](https://docs.retellai.com/deploy/custom-telephony)[(2)](https://docs.retellai.com/deploy/twilio)[(3)](https://docs.retellai.com/deploy/telnyx): - The termination SIP URI from Step 1 - Username and password if using credential-based authentication - The `outbound_allowed_countries` parameter with country codes (e.g., “PE” for Peru)[(4)](https://community.retellai.com/t/enable-israel-972-for-outbound-calls-on-my-account/781) When creating or updating a phone number, specify `outbound_allowed_countries` as a list of ISO 3166-1 alpha-2 country codes[(4)](https://community.retellai.com/t/enable-israel-972-for-outbound-calls-on-my-account/781). If not set or empty, calls to all countries are allowed by default, but your telephony provider must also support those destinations[(4)](https://community.retellai.com/t/enable-israel-972-for-outbound-calls-on-my-account/781). **Supported Transport Methods:** - TCP (Recommended)[(1)](https://docs.retellai.com/deploy/custom-telephony)[(3)](https://docs.retellai.com/deploy/telnyx) - UDP[(1)](https://docs.retellai.com/deploy/custom-telephony) - TLS[(1)](https://docs.retellai.com/deploy/custom-telephony) For different transport methods, append to the SIP server URL (e.g., `sip:sip.retellai.com;transport=tcp`)[(1)](https://docs.retellai.com/deploy/custom-telephony).
