Twilio Sip Trunk and IVR Logic with Whatsapp Automation (Template accepted) and Transcription

I would like to setup a sip trunk inside twilio for outbound calls only, with a different cheaper provider (zadarma for ex.). If its possible transcribe all incoming and outbound calls to portuguese (brazil) and sent to AmoCRM(OpenAPI). Also i need to setup a IVR that has a greeting welcome message and then if it rings about 8 times and nobody answer, then the ivr takes again and a recording says: All operators are busy right now, please press 1 to receive a Whatsapp Message and continue (if it's on landline, manually insert mobile phone) and send the template automatic or Press 2 to receive a call (then integromat create a task (list) into AmoCRM(openAPI) to a user to call this contacts that we have missed calls.
