Hello,
I have gone through google and through the forum here but I am unable to find an solution to our problem.

No users can make outbound calls. The phone displays 404 not found error on the screen. (Ubiquiti UVP)
The activity logs on 3CX show 05/17/2017 1:18:47 PM - [Flow] Target endpoint for 214******** can not be built!
I did a packet capture and the INVITE, 100 Trying and 404 Not Found output is below.

Does anyone know what i'm doing wrong? Thanks in advance for your help.

Hi dz,

I am just putting it out there as it is the first thing to check. Have you created an outbound rule?

Cheers
Alan
 
Thanks for the reply Alan. That's a good question and it was one of the first things I checked and re-checked. I went as far as removing all rules for faxes and left only one single default outbound.
Rule Name = Default Outbound
Apply this rule to these calls:
Calls to number starting with prefix = blank
Calls from extensions = blank
Calls to numbers with length of = 10,11
Calls from groups = not configured
Make outbound calls on:
Route, 1 , Flowroute, strip digits 0, prepend = "flowroute prefix + asterisk" (example: 123456*)
 
I don't see the call taking any outbound rule in the logs provided.
Try creating a second rule, just as a test, but be more specific as to the first digit, or areacode.

Calls to number starting with prefix = 2
Calls from extensions = blank
Calls to numbers with length of = 10
Calls from groups = not configured
Make outbound calls on:
Route, 1 , Flowroute, strip digits 0, prepend = 123456*

Put it ahead of the other rule and try a call to that 214 number, see if that works.

It is unclear in your log where the 404 message is coming from, is there part of the log that confirms it is coming from your provider? If so, are you sending the correct digits when that prefix is attached?
 
leejor,
Thank you for the suggestions. The 404 was coming directly from the PBX. As it turns out it was my outbound routes. I had to create two separate outbound rules; one specifying a 10 digit length with *1 after the prepend and another specifying an 11 digit length with just numerical prepend.

Thanks again!
