Support

Hi Cloudonix team,

Inbound SIP calls to our domain rxcare.cloudonix.net are never answered.

What we see in the SIP traces (attached):

1. The caller (LiveKit Cloud, IPs 161.115.178.228 / 161.115.183.85 / 161.115.178.246 / 161.115.178.208) sends INVITE sip:8003@b45516ef-3ae1-314e-8fa7-93c0069e1ebe.sip.cloudonix.net
2. The border gateway replies "100 trying" and forwards the INVITE to APP.Core at 172.24.40.145:9067
3. APP.Core never responds. The border retransmits ~11 times over ~30 seconds.
4. The caller sends CANCEL, and the border returns 487.

All sessions stay in status "Precreated". Our Voice Application never receives a webhook request.

Our configuration:

• Default Voice Application: dograh-e442b93891b0 (Remote, CXML, POST https://dograh.rxcare.app/api/v1/telephony/inbound/run)
• DNIDs 8001 and 8003 bound to this application
• Inbound trunks (UDP, port 0, all Active): 161.115.160.0/19, 143.223.88.0/21, 153.57.128.0/18
• Account is on the 14-day trial plan

Your status page shows no SIP incident. Could you check why APP.Core does not respond for this domain? Also, does the trial plan restrict inbound SIP from inbound trunks?

Thank you,
Kevin Nguyen – RxCare
