Hi Guys,<br>
<br>
Firstly, big thanks for assisting me with the username and raelm issue
I was having - seems to have worked itself out nicely.<br>
<br>
I'm looking for some guidance on how to do the following the "right"
way:<br>
<br>
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.<br>
<br>
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.<br>
<br>
I'm open to suggestions here, what I need to achieve is the following:<br>
<ol>
<li>Don't want to load 10000 numbers at a time into my
usr_preferences database, as this could get very big</li>
<li>Need a way to check that the CLID we've loaded is checked against
the display name in the From header</li>
<li>Check must be quick to ensure we don't kill opensips doing 1000's
of db queries</li>
</ol>
I look forward to the assistance.<br>
<br>
Thanks<br>
Doug<br>
