SS7 as well as sip allow for remote hold. No media is transmitted at that point in Sip you save bandwidth in TDM you don't eat up a channel<br>

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

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal">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.</p>
