Pass extension from Twilio to Asterisk

I am using twilio to manage our IVR, to handle SMS, and for a few other things. After a user calls and goes through the IVR (for example they press 2 for sales or they say they want extension 205) I need it to hand off to Asterisk.

Setting up the trunk isn't my issue. I need to somehow tag it so asterisk knows how to handle the call. If they chose ext 205 on twilio, I need asterisk to automatically ring ext 205.

I am using a minimal version of asterisk basically for sip registration and voicemail and the rest is done by twilio.

Does anyone know if there is a way to do this in code? Or is my best bet to create a different trunk for each extension. That seems like it would get messy.

Correct solution is make IVR on asterisk. This solution also will be MUCH less costly.

But if you really want... On twilio setup via SIP tag

https://www.twilio.com/docs/voice/twiml/sip

set url to sip:0000+exten@your_asterisk_ip

On asterisk setup trunk to twilio server or allowguest=yes and default context to 'goext'

After that goext context something like this

[goext]
exten => _0000XXX,1,Set(ext=${EXTEN:4})
same => n,Dial(SIP/${ext},,o)

0000 replace with some random code, that required for prevent bots calls when allowguest=yes.
