I have made some corrections to my FreePBX configuration for Vapi, and both endpoint, AOR, and SIP registration are now working. However, I am still not able to hear the AI assistant during calls, and the AI assistant cannot hear me either. To help you better understand the issue, I have attached screenshots showing all relevant configuration files and settings. Could you please review my setup and advise on what might be causing the lack of audio in both directions? https://cdn.discordapp.com/attachments/1441148114332418260/1441148114789470370/Cattura.PNG?ex=69484a45&is=6946f8c5&hm=adc58ad5b42176913572b72152a8ff0bb4a8a142649f36d552dfc308730ba5ac& https://cdn.discordapp.com/attachments/1441148114332418260/1441148115368415242/Cattura2.PNG?ex=69484a45&is=6946f8c5&hm=ad56da6bb438f6f4ee3a090a87e6adab24c67a697afd0bafd3effddcf412c8ce& https://cdn.discordapp.com/attachments/1441148114332418260/1441148115728994376/Cattura3.PNG?ex=69484a46&is=6946f8c6&hm=5814de178a4fe6a1b41f9d8997f771648cf9a83c0203422ebfb26be458a90d1f& https://cdn.discordapp.com/attachments/1441148114332418260/1441148116157071420/Cattura4.PNG?ex=69484a46&is=6946f8c6&hm=5df4e1a79510b2e6750911431bf77010b431390e1faa2ab6ca4fa8a2f8010d56& https://cdn.discordapp.com/attachments/1441148114332418260/1441148116488294572/Cattura5.PNG?ex=69484a46&is=6946f8c6&hm=d0f0fd1be69999616f6b741ae332fb6c5f8e2cf9e9c50a337d01f3e2f00ba9e8& https://cdn.discordapp.com/attachments/1441148114332418260/1441148116823703592/Cattura6.PNG?ex=69484a46&is=6946f8c6&hm=a7ba846eda6d6b629b54cde3a3a2d8fe3f23edbeb780d81d065ba4e6df8507ac& https://cdn.discordapp.com/attachments/1441148114332418260/1441148117214036039/Cattura7.PNG?ex=69484a46&is=6946f8c6&hm=fc96fc5246f57b23457d3d3359b9119a36499c09b1acd8589a496a9a3a5e8f68& https://cdn.discordapp.com/attachments/1441148114332418260/1441148117595590666/Cattura8.PNG?ex=69484a46&is=6946f8c6&hm=fc66c096a9527e6b01fe0bb7507e3364cabe9bd197c5548a29084811df8367c6& https://cdn.discordapp.com/attachments/1441148114332418260/1441148117935198389/Cattura9.PNG?ex=69484a46&is=6946f8c6&hm=6502931609fa3e4262b7d557c95c77cd81120bf04cca7761b50a8125cf772c8b&

Thanks for sharing your configuration details. To help narrow down the cause of the audio issue, could you confirm whether your Vapi Assistant configuration includes both a valid Phone Number ID and Assistant ID, and that a Text-to-Speech (TTS) provider is selected? Missing these can prevent audio in both directions according to the documentation. Source: - [Vapi Support Bot Discord Thread](https://discord.com/channels/1211482211119796234/1370485222214336564)
