Hi, here is my problem :
I have a ring group ringing 4 phones. Three phones are Grandstream ones supporting Alert Info.
I’m using Alert Info in the Inboud route to select a distinctive ring when calls are coming from the external trunk.
My problem is that one of the phone, a siemens 450IP DECT phone, don’t like Alert Info. When it receive an Alert Info, it simply does not ring.
I doubt that Siemens will correct this problem.
So my question is :
Is it possible to disallow Alert info selectively for an extension ?
Thanks for your help,
