RE: Fetching MSISDN in Kannel

Information regarding the MSISDN vanishes at the border between the PLMN
and the Internet. This is either the RAS server for CSD or something 
close to the SGSN in GPRS. If you don't have access to either one, you
can only depend on tokens voluntarily sent by the client's user agent.

So, what you want to do requires either support from your users or from
the network operator. Developers bemoan this problem since the dawn of 
WAP.

Betreff: Re: AW: Fetching MSISDN in Kannel


Thanks for the response. Is there any other identifier that I can use to 
identify the user? I have to log the requests and responses from the user 
and replay the response on receiving the same request later from the same 
user. The IP address can be used to identify the user while simulating and 
testing. But, how can this be done in actual wireless environment. Any 
pointers in this direction will be helpful.
