Called number does not exist

[AndyA]

Hello,

Our PBX stopped dialing outbound with the msg " Called number does not exist " inbound calls are fine.
log shows the following:

Date/Time	From	To	Talking
09/06/2021 5:11:36 PM	Reception (000)	0449802178	Not Answered
09/06/2021 5:11:36 PM	Reception (000)	0449802178	00:00:04

I did tried to call a number adding 1 as prefix, it gave me the following event log:

• Call or Registration to 10449802178@(Ln.10000@Crazytel SIP Trunk) has failed. 103.137.xx.xx replied: 500 Service Unavailable; from IP:103.137.xx.xx:5060
  SIP Server ID: 12294 09/06/2021 5:05:07 PM

whereby when dialing the correct number, nothing is logging in to event log.

Please advice.

Regards,
Andy

Hi @AndyA

Check your outbound rules to make sure nothing is blocking you there and try again. Check your activity log for errors when dialing the correct number.

500 Service Unavailable; from IP:103.137.xx.xx:5060

If the 103.137.xx.xx IP is your providers IP then you should speak with them.

Looking up Crazytel takes me to an Australian site.(please correct me if you are located in a different country) Unless you have removed digits, from the examples you posted, I suspect that the numbers are not in the correct format, as expected by the provider. As suggested, confirm with them, that you are sending digits that they are able to process.

routing checked , its fine. I have another customer with the exact same setting and its working.

Yes that is provider's static IP , I will check with them as well
Thank you for your help

...and make sure that it is not something to do with the caller ID you are sending. Some providers will reject calls if they don't consider the CID "correct".
