asterisk users - Jun 2004 - incoming cid translation tables

How does one do translation for calls that come in from other pbx's
where the incoming caller ID is an internal extension number on their
pbx?  Eg.  when I get a call from Free-World-Dial the CID shows up as
"429102" which is essentially their internal extension number sans any
routing prefix.  To dial the number back I need to dial the extension
with FWD's routing prefix prepended or 1-393-942-9102.  Is there some
simple way to route all the incoming FWD calls to a context that
prepends "393-9" to their 6-digit prefixes?  (And for extra credit
"393-99" to their 5-digit prefixes?)  Unless I can fix up their CID,
the dialback buttons on the phone (and in voicemail) are useless.

Looks like you and I are doing the same thing.  My plan is to implement
an AGI script (PHP is my weapon of choice) which will "normalize" all
incoming CID information, to prepend 1-393-9(9) to incoming FWD numbers,
1-700 to incoming IAXTel numbers, 01149 to incoming sipgate.de numbers,
etc.  My BV numbers also need the "1" prepended for redial --
Shouldn't
be a big deal, I'll let you know once I have mine done.  If anyone else
has a solution already, I'd love to save myself the work.

wolfgang,

Here's how I 'fix' my caller id for calls from FWD...

[fwd]
; routing for calls from FWD
exten => _X.,1,SetCidNum(*393${CALLERIDNUM})
exten => _X.,2,Macro(sipexten,1000,${KITCHEN},fwd)
...


Best Regards

There were a few suggestions on this, but I thought I'd put this one in.

Each of my inbound 'lines' go to a specific context, which fixes up
issues
with the numbering (extension and callerid) and then routes to a main
context for inbound traffic.

Example:

[fwd]
; Inbound traffic from FWD

; No callerid, nothing to fix
exten=_X./,1,NoOp

; Fix callerid on 6-digit numbers
exten=_X./_XXXXXX,1,SetCIDNum(3939${CALLERIDNUM},a)
; Fix callerid on 5-digit numbers
exten=_X./_XXXXX,1,SetCIDNum(39399${CALLERIDNUM},a)

; Jump to the normalised inbound-traffic context
exten = _X.,2,Goto(inbound-traffic,${EXTEN},1)
