6. Your problem:

Hi all, we have set up a pilot number for a hunt group round robin. But after the call has been routed, we can't get the original pilot number which has been dialed.

eg.
We have a pilot number "200" which forwards all calls to 201 until 209 round robin, we also have a pilot number "300" forwards calls to 201-209. It means that user can dial both 200 and 300 to ring at 201-209, but my question is, how can we differentiate the 2 kinds of call? On the SIP UA we just can received the callee as register number(201-209) no matter which pilot number(200 or 300) has been dialed.

Can we retain the dialed pilot number? This is a very useful feature in the IRV system, but I don't know how to do configuration on the brekeke pbx.

Your help will be appreciated!

create an ars like
matching pattern
To=sip:200@

deploy pattern
From="200"<sip:200@ip>

Hi hope, thanks for your reply.

But your method will replace the callerID(caller's number) if I'm not wrong. I have to keep both callerID and dialed number in order to perform correct operation.

Is there any other methods I can use?

maybe SCA meet your needs, have a look
