[cisco-voip] dialtone after disconnect on vg224

[Bernhard Albler]

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 <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

bernhard

	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?
