<FONT FACE="Monaco, Courier New"><SPAN STYLE='font-size:11pt'>You have to parse out the NDPI and RN values...<BR>
<BR>
Just use a regex like ^(?:+1|1)?([2-9]\d{2}[2-9]\d{6});ndpi=(*.);rn=([2-9]\d{2}[2-9]\d{6})$<BR>
That will get dialed digits in $1, ndpi value in $2, then LRN in $3,<BR>
<BR>
I would warn against trusting the LRN you are sent if you do not explicitly trust the customer sending you said LRN... Its not like its hard to spoof the LRN replacnig the LRN from a high cost ratecenter with a low cost ratecenter<BR>

I thought "Caller-Destination-Number" was always the cleaned dialed number (i.e. 5551234567) - is this not the case?<BR>

A SIP call comes in that was previously dipped. I'd like to be able to<BR>
have "rn" and "npdi" available as channel variables that I can use in<BR>
regex expressions. Is there a way to configure FreeSWITCH to put "rn"<BR>
and "npdi" into separate channel variable?<BR>
<BR>
So far, info application shows me the following channel variables that<BR>
contain LRN:<BR>
<BR>
Caller-Destination-Number: [5551234567;npdi=yes;rn=5555550001]<BR>
variable_sip_req_user: [5551234567;npdi=yes;rn=5555550001]<BR>
variable_sip_req_uri: [5551234567;npdi=yes;<a href="rn=5555550001@1.2.3.4:5060">rn=5555550001@1.2.3.4:5060</a> <<a href="http://5555550001@1.2.3.4:5060">http://5555550001@1.2.3.4:5060</a>> ]<BR>
<BR>
I can probably dissect those and put "rn" and "npdi" into separate<BR>
variables. But this means extra steps in dial-plan. In case there is a<BR>
built-in way to accomplish the same task, it would be great!<BR>
<BR>
Could you please let me know.<BR>
<BR>
Thank you,<BR>
Victor<BR>
