Hi I think I may have seen what is wrong, my problem I was getting the error when I was getting the confirmation link, whereas I think you are getting it when you are intially submitting it for a new user, if this is true then ur calling the scripts under reg/ directory in serweb. Also my version of serweb is $Id: INSTALL,v 1.15 2005/02/01 09:34:19 kozlik Exp $ from the INSTALL file, hence my configs are different, and now I have changed the system so that I dont add names to subscriber but add that to alias, and add the number to the subscriber table. Anyhow in short what you need to look at is the registration page, it will be calling a function which is adding the alias, this is in the data_layer directory. Now in this function the alias must be using fifo to add to the the alias directly. This is where the error is. Sorry I cant be of more help I wish I had documented it better, but I was flying through it like a headless chicken But do note in the long run adding names to subscriber is NOT the best way to go, since people will want to dial numbers, which they can, if they are in alias, but if you want to add voicemail etc at alater date, then to connect to the voicemail box from a handset dialing a number which aliagns to the users number is better than trying to dial a name...well thats my experience anyhow Iqbal Mr Greg Plater wrote:
