Hello there, I have a number from Telynx added to vapi through sip trunk and it wasn't stable... Now I added the number in the dashboard but it wasn't working, is this because it has been configure to sip beforehand or because it was duplicated in vapi? Am I supposed to erase the sip trunk configurations? What do I do?

Hi there! 👋 I understand you're having issues with your Telnyx number in Vapi. I don't have specific step-by-step instructions on how to remove SIP trunk configurations in Vapi, but I can definitely help explain what might be happening with your number. Based on the information I found, there's likely a conflict between your SIP trunk configuration and dashboard configuration for the same number. According to [Discord discussions](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1339952678150868992), when the same phone number is configured in multiple places, you might encounter an error like "Multiple accounts are attempting to route the same phone number from the same carrier." The recommended solution is to "delete all of the existing SIPs with this number on Vapi and then try creating new again" as mentioned in the same source. This suggests that having both configurations simultaneously is causing the instability you're experiencing. For Telnyx specifically, when setting up SIP trunking with Vapi, you should use: - Gateway IP:

sip.telnyx.com

- FQDN:

sip.vapi.ai

- Port:

5060

If you decide to reconfigure, the correct procedure is to: 1. First create the trunk (inbound and outbound) 2. Then create the phone number 3. Finally link the number Would you like me to help with any other aspects of your Telnyx and Vapi integration?

First, you need to remove all of your credentials for numbers related to SIP trunking with Telenyx. Then, you need to remove the Telenyx number from the dashboard and add it back to the VAPI dashboard.

Okay thank you 😌🙏🏻🙏🏻
