CallerID does not come in E.164 format, only in local format

QUESTION:

hello ! from Ukraine DID caller ID is not coming in the E.164 format.

It is coming in the local format like 80519539xx, but must be 3805019539xx. Is it possible to fix this?

ANSWER:

Your DID number is forwarded with CLI as it is, i.e exactly how we get it.
Unfortunately, we cannot make any changes in the Caller-ID format on a particular number. 
However,we are checking what can be done in this case.
Thank you for your patience in this matter.

Thank you for using DID World Wide services!

FAS - Fast Call Answer - Call is answered instantly even if the other end has not answered yet. The user is ALWAYS charged for the call.

QUESTION

Hello! People who called this number are getting an ANSWER before I pick up the phone.
The same if I don't pick up for a long time - they have on the screen and in the billing invoice 
from their providers that the connection was successful, like ANSWER, and I'm paying money 
for nothing.
This is a fake answer signal (FAS) and no good from your side .
Maybe this problem is not from you. You are getting this, but I'm have big problems 
with people who are calling me!

ANSWER

With mobile phone service providers (unlike with landline phone service providers), 

you will be billed from the second you hit the Send button.

Thus it's normal that the mobile caller is billed even if the call isn't answered on your side.

Configuring DIDWW for receiving calls to DID

The problem with this DID Provider is that it sends calls from many IP addresses:

204.11.194.34
204.11.194.35
204.11.194.36

First create a new provider (most important parts are marked in red, Device ID can/will be different in your case - REMEMBER IT!!!):

Then in /etc/asterisk/sip.conf, at the very end, enter (copy/paste):

[didww_116]
type=friend
context=mor
accountcode=5
host=212.150.36.116
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_21]
type=friend
context=mor
accountcode=5
host=212.150.88.21
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_34]
type=friend
context=mor
accountcode=5
host=204.11.194.34
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_35]
type=friend
context=mor
accountcode=5
host=204.11.194.35
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_36]
type=friend
context=mor
accountcode=5
host=204.11.194.36
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_37]
type=friend
context=mor
accountcode=5
host=204.11.194.37
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_38]
type=friend
context=mor
accountcode=5
host=204.11.194.38
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_39]
type=friend
context=mor
accountcode=5
host=81.85.224.39
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_40]
type=friend
context=mor
accountcode=5
host=81.85.224.40
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_41]
type=friend
context=mor
accountcode=5
host=81.85.224.41
disallow=all
allow=g729
allow=alaw
allow=ulaw

[didww_42]
type=friend
context=mor
accountcode=5
host=81.85.224.42
disallow=all
allow=g729
allow=alaw
allow=ulaw

========== VERY IMPORTANT!!! ==========
accountcode should be == Device ID in your Provider window. In our case it is == 5. Change it according to your correct value!!!

DID configuration

Then:

• Save the file.
• Reload Asterisk.
• Create DID - IN E.164 FORMAT!!!!!!!!
• Assign to a DIDWW Provider.
• Assign to some device.
• Configure correct routing (mapping) in www.didww.com.

Configuration in www.didww.com

We will assign a Thailand, Bangkok number to our server:

First we need to create "mapping", that is, the route to our server:

After this, we need to assign our DID to our just-created "mapping":

Troubleshooting

Watch Asterisk CLI to see what's happening.

Maybe you have DID in the wrong format - for example, not E.164 compatible?

If you are using IAX2 connection from DIDWW, create a Provider with type = IAX2 and paste sip.conf configuration into /etc/asterisk/iax.conf.
