Hello! I followed the instructions: https://zadarma.com/support/instructions/vapiai/ https://docs.vapi.ai/advanced/sip/zadarma Outgoing calls and campaigns work correctly, but incoming calls do not, even though the settings specify permanent forwarding to 38093ХХХХХХХ@sip.vapi.ai.

Looks like you’ve got the outgoing side working fine, but the incoming calls are still not coming through. I’ve dealt with this type of setup before and can help figure out what’s blocking it. do you know if the calls are actually reaching Zadarma before they get lost, or not even hitting their side at all?

Calls to Zadarma are coming through. I disabled call forwarding and checked via their softphone.

If Zadarma confirms the call is forwarded and Vapi returns “Number not found,” it usually means the SIP address isn’t mapped correctly inside Vapi or the number format isn’t matching what Vapi expects. I can help check the routing rules and make sure the endpoint is set up to accept those calls. Would you like us to discuss this more privately?

yes

Alright, let’s discuss this more privately, maybe over WhatsApp. You can reach me at: +2347019042229

I got exactly the same problem for a month already. Tried all the different settings, zadarma support and even different AI agents provider (it all worked there), so the problem is within VAPI. Please help. Can I also write to this number?
