It provides methods for receiving \s-1PCUM/8000\s0 data and for echoing them back or for sending and receiving \s-1PCMU/8000\s0 data. .PP It's used from method \fBrtp\fR in Net::SIP::Simple. .SH "SUBROUTINES" .IX Header "SUBROUTINES" .IP "media_recv_echo ( [ \s-1OUTPUT, DELAY\s0 ] )" 4 .IX Item "media_recv_echo ( [ OUTPUT, DELAY ] )" Receives \s-1RTP\s0 data and echoes them back to the sender. If \s-1OUTPUT\s0 is given it will be used as the file for saving the received data without the \s-1RTP\s0 header. .Sp \&\s-1OUTPUT\s0 might also be a callback which gets the payload as argument. .Sp If \s-1DELAY\s0 is >0 the data will not be echoed back immediately but with a delay of \s-1DELAY\s0 packets (e.g. with \s-1DELAY 10\s0 it will send back the first packet after it received the 10th packet). If \s-1DELAY\s0 is <0 the data will not be echoed back. If \s-1DELAY\s0 is not given or equal 0 the data will be echoed back immediately. .Sp If no traffic comes in for more then 10 seconds it will hang up the call because of inactivity. .IP "media_send_recv ( \s-1INPUT,\s0 [ \s-1REPEAT, OUTPUT\s0 ] )" 4 .IX Item "media_send_recv ( INPUT, [ REPEAT, OUTPUT ] )" Will read data from file \s-1INPUT\s0 and send them as \s-1RTP\s0 to peer. It will assume that each data block in \s-1INPUT\s0 consists of 160 bytes, which is right for \s-1PCMU/8000\s0 without \s-1RTP\s0 header. The \s-1RTP\s0 header will be added to the data. .Sp If it reaches the end of the file it will stop unless \s-1REPEAT\s0 is given in which case it will repeat the sending \s-1REPEAT\s0 times (if \s-1REPEAT\s0 is less 0 it will repeat forever e.g. until the other party hangs up). On stopping it will invoke the callback \fBcb_rtp_done\fR from the connection params for the Net::SIP::Simple::Call or if this is not given it will close the call by issuing a \s-1BYE.\s0 .Sp \&\s-1INPUT\s0 might also be a callback usable by \fBinvoke_callback\fR in Net::SIP::Util which returns the data to send. In this case \s-1REPEAT\s0 is not used. .Sp Incoming data will be written to the optional \s-1OUTPUT\s0 file like in \fBmedia_recv_echo\fR. The content from \s-1OUTPUT\s0 has the same format as \s-1INPUT\s0 or \s-1OUTPUT\s0 from \fBmedia_recv_echo\fR. .Sp \&\s-1OUTPUT\s0 might also be a callback which gets the payload as an argument. .Sp If no traffic comes in for more then 10 seconds it will hang up the call because of inactivity.
