You need to give that file write permissions in the ser configuration file. fifo_mode=0666. Ex: check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) port=5060 children=4 fifo="/tmp/ser_fifo" fifo_mode=0666 Then restart ser, this should fix your problem.

All that is fine But I have a error always saying "sorry -- cannot open write fifo" I have never done anything with fifo. Do I have to set it up If yes then how. Also I want to make calls through my serweb user webpage but I don't see any option of doing that. I can only see a option of IM in it, but that too does not work due to FIFO error. So any1 out there can help me out ...... Thanks Dipen K Gala Fidelity Investments System Company - Telecom Phone: (617) 563-2729 Email: Dipen.Gala(a)FMR.com
