Re: [Serusers] SER+Rtp proxy -> no voice going through

Hi all, I have found the following ser.cfg file

SER+RTP proxy combination in the mailing list. However, with this, no audio is going through. The call goes through, if i accept the call, no audio.

completely new to SER and SIP servers and still

through the manuals for the ser script. Any help

be appreciated. Thanks. - tareq # # $Id: ser.cfg,v 1.21 2003/06/04 13:47:36 jiri Exp
