Re: [Serusers] Using Aliases

12 May 2003

Hello,

The gateway should extract the number from the Request-URI which is
rewritten by the aliases. What gateway are you using ?

One more thing which is not related to the problem: use t_relay instead
of forward in your script.

  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
