[cisco-voip] dialtone after disconnect on vg224

[Lelio Fulgenzi]

Thanks so much Bernhard. I took a quick look at the doc and found this:
  Cisco CallManager 4.2 or a later release is running to enable fax relay, modem relay, dial tone generation after remote onhook and ground start FXS ports features. 
I'm running 4.1(3) but I'll still try it out. The SCCP with supplementary features doc said I needed 4.2 for PLAR with VG224 and I found that it worked with 4.1(3), so hopefully this will work.

Thanks again!

  Lelio,

   

  I had that issue with one customer about 1 ½ years ago. Basically the issue was that my analog devices (cordless and polycom conf phones) did (and do not) support any kind of disconnect supervision beside tone detection.

  I opened a case on the issue and basically the result was the following:

     * the vg224 expects the analog device to actually disconnect the call

     * unfortunately the stcapp was not capable of playing any kind of busy tone after disconnect

     * since the analog device was still offhook, the vg would start to play dialtone again after some time

   

  Workaround: convert the vg224 to H323, use ATAs or buy 7936s as a replacement for  the conf phones ;-)


  BUT, guess what:

  12.4(11)T  provides you with some flexibility there (recently added and my austria SE informed me about it):

  Quote from the TOI slide:

      Feature can be enabled/disabled via pots dial peer configuration. 

      Default feature is enabled and does not show up in running config. 

      A new option is added for tone sub-command under pots dial peer.

            dial-peer voice  xxx pots

            [no] tone dialtone remote-onhook

      No form of this command will disable this feature. 

   

      Note: This CLI option is available to all dial peer services. It is up to the service to 

      determine whether to utilize/enable it. Currently only STCAPP supports it.

   

  So I haven't tried out what happens, when you disable the automatic dialtone generation (dead air or a busy?). But I guess I would give it a try.

  Documentation at; http://www.ardentcom.com/univercd/cc/td/doc/product/software/ios124/124newft/124limit/124x/124xe6/htrelay.htm#wp1086931

   

  So maybe this feature isn't as silly as wanting to forward secondary lines (which is OUTRAGEOUSLY silly of course ) ;-).

   

  Regards

    What protocol are you running on the VG224? MGCP?

    Right now, on my VG224 port, when the other party hangs up, I am presented with dialtone. I would rather the VG224 disconnect the line. This is particularly useful for cordless phones that someone would just put down rather than hang up.

     

    Is there a setting that I'm missing?

     

    Or is everything working as designed and I'm asking for something silly like forwarding secondary lines?
