Re: UC520 Can not complete conference

Once you change to hardware conferencing, all conferences (including three way) are handled by the on-board DSP's. You are missing the ad-hoc ephone-dn, that's why it doesn't work. More info on:

Re: UC520 Can not complete conference

Hi Marcos,

After putting in the "conference ad-hoc" command under ephone-dn 1 dual-line

but it not allow me to key in the "call-forward busy 401 ' and " call-forward noan 401 timout 10" for transfering call to voicemail pilot 401. Any thought? Thanks

Re: UC520 Can not complete conference

You cannot do it on these existing DN's assigned to phones. You have to create new ephone-dn and these will just have that ad-hoc command.

Re: UC520 Can not complete conference

Hi Marcos,

I created a new DN, and it takes the conference ad-hoc command , but it did not take the "call-forward busy 401 and call-forward noan 401 timeout 10" commands, and claimed "Remove DN special mode configuration first", not sure what is means. following is the screen capture.

Please advise.

Thanks

Re: UC520 Can not complete conference

You need to remove all commands except "ad-hoc" and "number". It is explained in the document I sent.


Thanks,

Re: UC520 Can not complete conference

Is this means the hardware ad-hoc conference feature could not co-exist with the busy call-farward to voice mail pilot on that dn ? Thanks
