Cisco Codec Control

Hi All,

I have been using iRule for a while now. I have built a system that controls equipment via a global cache gateway. The system controls a Cisco SX20 codec using IR. I learnt the IR commands and although they do work it can be a bit hit and miss on whether they work. I have tried using telnet successfully from a laptop and from an app on an android device. Hovever I cannot get telnet to work via iRule. iRule sees the codec but the commands don't appear to work.

I am actually managing to control the Codec with HTTP commands via iRule but i would prefer to use telnet.

Has anyone else used iRule to control a Cisco codec with telnet?

Any help would be gratefully received.

Regards

Gary

  • How did you manage to control the codec via HTTP? I've been trying and it doesn't answer me.

    Any especial port of control on the codec?

  • In most cases, controlling a component via http is essentially telnet over an IP connection. The commands are the same, just the transmission is different.

    Do you want to use a telnet client on a pc? In that case, be sure you are using the right IP address and the right port. These are likely the same as your http setup.

    When testing telnet, be sure other remote connections are inactive. Sometimes only 1 connection at a time is possible.

    Many protocols end commands with \x0D, or \x0D\x0A. This is the format in iRule for the hex numbers 0D and 0A. In many cases, a telnet client will use a different format, such as \r\n. You may have to modify the end of your commands to match the telnet program.

    Do a search for 'Hercules' to find more posts about telnet.
