[Serusers] Using Aliases

I would appreciate any help on the use of the alias function. I presently have SER pretty much iorking way way I need with one exception - Aliases. I have a PSTN gateway set at 201.153.164.233 and any call that is sip:9xxxxxxx@global.dds is forwarded to the gateway which then dials on PSTN to xxxxxxx The set up works fine normally ie. Dialing 925217801 on my ATA186 connects me to 25217801 However I have an alias setup 8118118 pointing to sip:925217801@globaldds.com Dialing 8118118 on my ATA changes the uri to sip:925217801@globaldds.com so it is forwarded to the gateway. But the gateway still seems to receive sip:8118118@globaldds.com as the "To" address and dropping the first digit the gatway dials 118118 on the PSTN I have attached my ser.cfg and Ethereal captures for the direct call that works and the alias call that does not. Thanks & Regards, Dinesh
