Hey @Shubham Bajaj An error occurred in this call: call.in-progress.error-sip-telephony-provider-failed-to-connect-call This error occurs in some calls when using the BYO sip trunking. The provider assures that calls dont have a simultaneous limit. Call ID example where it happened: 35fad6e3-c0cf-4801-bc25-a1e4fa5bf3c6

Hey! To help track down this issue, could you share: - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!

Hey shubham, an example call was callId: bfaf91b8-2703-4da9-af29-a6a955ba5cf7 / It doesnt show me a timestamp, I got the error "call.in-progress.error-sip-telephony-provider-failed-to-connect-call" I expected the call to go through and not show any errors https://cdn.discordapp.com/attachments/1373000873046704280/1373277305073565907/image.png?ex=6829d3a7&is=68288227&hm=1dc74b0ef48c765d33a0a7ce688951e42902a3e9d2e109071a1d3a7937afacaa&

@Shubham Bajaj I've done some work with @Ω ΣκοτάδιΣεληνόφωτο Ω trying to assert the issue. We connected them to Cloudonix to review, and it seems like calls that appear as generated on VAPI actually never made it to Cloudonix, as in, we never received the inbound invite from VAPI for it.

Hey @Nir S (CEO/Founder @Cloudonix) , I’m currently away and expect to be back in ~4 hours. I’ve seen your message and will review it as soon as I’m back online. If it’s urgent, feel free to ping me—I can jump in sooner if needed.

Hey Shubham any updates?

I think you tagged wrong person lol

My bad @Kings_big💫

Can you check with your telephony provider?

OH is live, feel free to join-in and ask your questions. #1224791787332173844

We did, we even got Nir to help us and inside cloudonix he said that even they didnt receive the call from vapi's side

can you try making calls once again?

OMG it looks like it is actually working Sahil, i tested it in a small scale, so i wont give you 100% certantity yet, but tomorrow we will do a test with around 3k calls for one of our smaller clients to validate before pushing the sip changes into production. Thanks SOOO much Sahil!!!!

sent you the PCAP in DM.
