[VoiceOps] Signaling hold to the PSTN

in my opinion remote hold will be used less and less as things move to packet switched and bandwidth becomes less and less of an issue. Problem being that most people do not understand the standards and would just prefer to configure local hold

Shouldn't the local switch just play hold music into the network, and the other side be completely unaware of hold at all?

What has been your experience in signaling holds to the PSTN?  The more everyone converts to SIP and peers with our carriers, the more stacks we see on the far end.  A growing number seem to have trouble accepting any kind of hold SDP signals such as a=inactive/sendonly, quad zeros, etc.

Is this vexing you too, or is it just me?
