Hi @Tin Nwe Win,

Can you confirm who the IP 10.19.74.146 belongs to? Are you using a gateway? This seems to be a response telling the PBX that the number is currently busy as per the message.

Does this happen for all outgoing calls or only this specific number? Does this happen every single time when you call this number?

IP 10.19.74.146 belongs to our ISP provider.

This happened for all outgoing calls.

Please kindly advise me for above issue.

Hi @Tin Nwe Win,

If the message is coming through for all calls, this would be something you'd need to investigate with your provider. We (the PBX) can only see the information coming from the gateway / router, and that information is telling us that the line is busy. This may be a problem between the gateway and provider or specific to the provider.

Now we are connecting the SIP trunk fiber cable with 3CX server without using the Gateway.
Can you please advise what I need to check for this

All of the extensions can not make outbound call that's why please kindly help how can I check this issue.

Hi @Tin Nwe Win,

Is your IS provider also your SIP Trunk provider? Are they a supported provider: https://www.3cx.com/partners/sip-trunks/

If not, I would really suggest speaking with them for more clarification, but also remember to adhere to our supported network configurations guide @Saqqara posted above.

 

[Tin Nwe Win]

Thank you very much for your help.

Sure thing @Tin Nwe Win, feel free to update me when you've spoken with your provider so we can get to the bottom of this.

@VasilisV_3CX Thanks
May I ask one more question that can SIP trunk connect directly to the 3CX server without connecting firewall or gateway/router?
Thank you in advance for your support.

Thank you in advance for your support.

This is a question for your SIP provider, normally if the company supplies a gateway / router it is required

@VasilisV_3CX @Saqqara Thank you for your support.

I will get back to you after I check with ISP Provider.

@Saqqara @VasilisV_3CX After checking with our provider, the outbound call is working now.
Thanks you
