SIP Trunking Troubleshooting
Half of my Inbound SIP Calls are failing
Make sure you are accepting calls from all the IP listed above. Most common reason for failed inbound call is that you system is rejecting call from few IPs.
We can not make outbound SIP calls.
This can be because of some missing configuration or wrong format in SIP Signaling :
Make sure the IP you are sending call from if added to your account.
While adding the IP address, make sure Termination is Enabled. Based on those settings we decide whether calls will be terminated or not.
For USA and Canada call must come with "1" Prefix + 10 Digit phone number. Example 19499300360
For International it should be 011+Country Code+Phone number.
International Calls are Failing
For Security and Protection, be default international calls are disabled. Contact your Account Rep to allow international termination.
I can make only 1 Outbound Call
