@User We’re running into an issue with inbound calls using an Australian number (+61) and wanted to check if anyone has seen something similar. Context (no confidential details): We are connected to Retell via Custom Telephony (SIP). Same PBX, same SIP trunk, same Retell agent. Spanish numbers work perfectly with this setup. When we switch to an Australian geographic number (+61), inbound calls stop working only in Retell. The Australian number itself is active and works correctly at carrier/PBX level. Important detail: Nothing else changes in the configuration (agent, SIP routing, PBX logic). The only difference is the country of the DID. Question: Are Australian geographic numbers (+61) officially supported for inbound calls via Custom Telephony / BYON? Are there any country-specific limitations or validations for AU numbers that could cause inbound calls to be rejected or ignored? If anyone from the team or community has experience with AU numbers + custom telephony, any insight would be appreciated 🙏 Thanks!
