An error occurred in this call: call.in-progress.error-sip-outbound-call-failed-to-connect
Dear team,
We are currently experiencing difficulties with simultaneous call attempts, resulting in a significantly low success rate.
When attempting to place outbound calls, over 80% of them return a SIP connection error, requiring multiple retries before the call successfully goes through.
We believe this issue is not related to IP whitelisting or SIP misconfiguration, as the Vapi IP addresses 44.229.228.186/32 and 44.238.177.138/32 are already included in our provider’s firewall allowlist.
Given this, we kindly request your technical team’s support in investigating and resolving this instability.
Thank you in advance for your attention. We look forward to your response
