I'm implementing the "Call Transfer" feature with Vapi + Vonage, but I'm encountering a strange bug: Case 1: I call (with my French number) the assistant, which has a French number (Vonage), and ask to be forwarded to another French number → Forwarding does not work ❌ Case 2: I call (with my French number) the assistant, which has a US number,(Vonage), and ask to be forwarded to another French number → Forwarding works ✅ It’s as if there’s a specific restriction for the French number, whereas forwarding from a US number to a French number works fine 😪. Has anyone encountered this issue and found a solution?

Hey! To help track down this issue, could you share: - The call ID of both cases This would really help us figure out what went wrong!

I talked with someone at vonage and apparently they have restriction for forwarding on french mobile number

DM me, I may be able to help resolve this issue.
