Hi Iqbal, Jan, I changed my log to /tmp/fifo in my ser.cfg and the serctl.dat file. I then tried adding an alias: Serctl alias add 7890 sip:aisling@x.x.x.x Again I got the 404 flags expected error and I checked the /tmp/fifo file. It was empty. I then did /opt/ser/sbin/serctl fifo ul_add aliases aisling(a)x.x.x.x 7890 0 1.00 0 128. (It would work unless I added those 4 parameters) It said 200 Added to table and the following appeared in my new log file: :ul_add:ser_receiver_28642 aliases aisling(a)x.x.x.x 7890 However while this said added above. When I dialed 7890 to reach the aisling(a)x.x.x.x client, a 404 was sent to my phone. Many Thanks, Aisling. -----Original Message----- From: Iqbal [mailto:iqbal@gigo.co.uk] Sent: 24 August 2005 12:29 To: Aisling O'Driscoll Subject: [Fwd: Re: [Serusers] ul_add flag and serctl] could try this -------------------Legal Disclaimer--------------------------------------- The above electronic mail transmission is confidential and intended only for the person to whom it is addressed.
