Incoming number changed for outbound?

[ericmachine]

Hi everyone,

I configured elastix as below:-

We have E1 line with 200 numbers, 30 channels. I had configured the right numbers to link from my voice gateway to elastix.

company number: 035XXXXXX1
direct number: 035XXXXXX2 (link to ext 1000)

inbound and outbound routes configured correctly

ext 1000

follow me: HUNT
- 1000
- 10001 (my iphone's bria soft phone client)
- 0193XXXXX9# (this is my hand phone number)

Below are the tested scenarios:-

a. Customer (0125XXXXXX - his mobile number) called my direct number 035XXXXXX2. It will show the customer handphone number at my Bria3 softphone or Yealink SIP-T28P. Tested OKAY.

b. If I don't pick up on point a, then it will go to my iphone's bria. At this time, it will show the customer handphone number (0125XXXXXX). Tested OKAY.

c. Now if I don't pick up on point b, elastix will dial to my hand phone number here 0193XXXXX9# (as configured in follow me, check above). So when I get a call, it will show my company number (035XXXXXX1) instead of the customer's hand phone (0125XXXXXX). Tested FAIL.

Why is point c not showing the actual customer's mobile number?

My trunk (outbound route using this) as follows:-

- connected to my E1 line (only this connection on my system, no other ITSB or SIP providers)
- Outbound caller id, my company number (035XXXXXX1). If i don't set this, there's no difference too. Point c still happens.
- Outgoing Settings:-

Trunk: MyE1

host=192.168.1.2 (my elastix server ip)
type=peer

- Incoming Settings:-

User Context: MyE1-incoming

host=192.168.1.2
type=peer
context=from-trunk

- the rest all default. The settings above should be okay as it works for my office's Yealink IP Phone to call mobile number, other local number as well as receive.

Any help on this? Thanks in advance.

ericmachine,

First of all this is normal operation. This functionality is very much dependent on the carrier.

95% of carriers in meeting their countries anti-spoofing laws, will not allow you to present a CID that is not owned by you.

A simple test is to set a CID (that you don't own) on one of your outbound routes and make a call to your Mobile. It is expected that it will not show your selected CID, but show the default CID of your E1/T1 line.

Another quick test, is change this outbound CID to one of your range (e.g. xxx4) and this should work.

Some carriers allow you to present other numbers (e.g. other numbers that you own e.g. an old PSTN number), but you normally have to show ownership.

So as you can imagine, presenting a CID of a caller to your system to go out via your ISDN line, the carrier will normally reject it and replace it with your default CID.

Some carriers may not adhere to this regulation, and you might get lucky but they are few and far between. Some SIP providers are more likely to provide this ability, but again, they are being brought into line with regulations, and while they may provide it one day, you could find it turned off the next day and should not be relied on in a commercial situation.

All our calls (that get redirected to a Mobile phone), we make go out on a specific CID, so at least we can tell it is a redirected call from our PBX system.

Hope this helps.....
