Hi Richard,

Big thanks, been playing around with the dialplan module - really rocks.

Just a question though, I'm using $fn to check the CLID, however, $fn has double-quotes encasing it. Is there a way that I can strip the double quotes from $fn (I'll copy it to an AVP first obviously) before passing it to dp_translate, otherwise, it doesn't match my regexes.

Thanks
Doug

Hi Guys,

Firstly, big thanks for assisting me with the username and raelm issue I was having - seems to have worked itself out nicely.

I'm looking for some guidance on how to do the following the "right" way:

We currently have some wholesale clients signed up with us now, and they have a few 1000 numbers in their assigned number ranges. We'd like to transit their CLID, but I really don't want to troll through my usr_preferences to pull 1000 CLID, and then identify which number they're sending and checking to see if it exists.

I was thinking of loading a range of sorts using a regex, like 1800777XXXX which would be a 10000 number range. Then when the client sends us their CLID in the display name section of the From header, say 18007775566, we could check against the XXXX portion using a regex, and if it returns true, we accept the CLID and instruct the C4 to present the CLID. If not, we return a SIP error saying "Invalid CLID" or something like that.

I'm open to suggestions here, what I need to achieve is the following:

   1. Don't want to load 10000 numbers at a time into my
      usr_preferences database, as this could get very big
   2. Need a way to check that the CLID we've loaded is checked
      against the display name in the From header
   3. Check must be quick to ensure we don't kill opensips doing
      1000's of db queries

I look forward to the assistance.

Thanks
Doug
