Solved Flowroute : 407 Proxy Authentication/E164 format

[SFRAZ1]

Hello, Everyone I have a small problem, My client was using a 3cx with the management console and everything was fine as we used *480XXXXXX instead of +1480XXXXXXX in the DID section of the trunk.
now we are using an SMB for the client and in SMB we don't have the option to add * we have to use +1 in the field.

I called Flowroute and using a test environment we found out that if we use +1 in the 3cX with the management console it gives the error 407 Proxy auth error and the call never gets a tone.

Flowroute is tested and supported to use the number in E164 format as per guideline: https://www.3cx.com/docs/sip-trunk/flowroute-usa/
You need to clarify with Flowroute why they do not accept it.

Yes, I called them they said the issue is from 3cx. Like I said it works when I have a * before the number but does not work with +1 in 3cx.
They mentioned the 407 error.

unfortunately, I have a license that expires in 2 days I need this fixed so I can get the customer the correct subscription. I do not mind if you use one of the tickets for this its just urgent thanks.

Do you also have DID numbers in this format or just the main trunk number?

 

[SFRAZ1]

Yes, all the DIDs have to be in this format, otherwise, if they are in e164 format they will not work.

Creating a new sip trunk with only the main trunk number in E164 format(without any DID) has the same issue?

 

[SFRAZ1]

yes if I create a new sip and in the main I use one did with E164 and I did not add any other DID still it beeps once and hangs up.

 

[TheodorosG_3CX]

Do you see the sip trunk as registered?

 

[SFRAZ1]

Do you see the sip trunk as registered?

yes

 

[TheodorosG_3CX]

So there is no issue with the Sip Trunk registration correct?
You are not able to make outbound calls? Are you able to receive calls?

 

[SFRAZ1]

if i give you access to my flowroute sip credentials can you create a sip on your account and see if it works?

 

[SFRAZ1]

when i tried calling out it gave me this error.

 

[TheodorosG_3CX]

Are you dialing the number in E164 format?

 

[SFRAZ1]

yes i tried dialing that format no luck.

 

[TheodorosG_3CX]

For all your attempts we receive this error: 34.210.91.112 replied: 403 International Calling Disabled
This is coming from Flowroute, what was their response on this?

 

[SFRAZ1]

I just submitted a ticket to them with this error, I do want to mention that when i call from outside to the main did of the sip i get no event log but when i call out from 3cx i get a event log.

 

[TheodorosG_3CX]

Let me know the update from their side

 

[SFRAZ1]

btw This has been the same for all my flowroute clients i have 3 clients on it. I wish you could test it using my sip info.
