Trying to set up outbound SIP using your guide here: https://relieved-yuzu-73a.notion.site/SIP-Outbound-Guide-997d66df35284295b7149fc10c82f3e8 For #3, when creating SIP credential, what value do you typically provide for "your-gateway-id"? (see screenshot) https://cdn.discordapp.com/attachments/1325895865642254336/1325895866170478702/image.png?ex=677d7440&is=677c22c0&hm=8815f8fd810367ec65aa242bcd94b4fc70bc09dff01965a20d2d174391c0b68f&

@amir The value for "your-gateway-id" should be the unique identifier for your SIP gateway. This is typically provided by your SIP service provider. It's a string that represents the gateway within their network, allowing the SIP service to route your outbound calls correctly through their infrastructure. If you're unsure what your SIP gateway ID is, you should consult the documentation provided by your SIP service provider or reach out to their support team for assistance. They will be able to provide you with the specific details required to configure your outbound SIP settings correctly.

We're just trying to trigger outbound calls through Vapi API -- how about in that case? Reason we're setting up SIP is to send DTMF tones through it, because default method doesn't seem to work for some phone calls.

@amir Gateway address can be used in two ways either as IPV4 Address like 1.1.1.1or as Web Adrress like my-sip-trunk.pstn.twilio.com both work fine.
