There has always been good information of one-way delay for voice stating below 150msec but lots of docs stating 200 will be fine. But what about for signalling! I have a centralised cluster deployment and phones across the world, all with local breakout. The Voice traffic will breakout locally so no delay however the signalling still has to go from phone &gateway to CCM. Do we have any figures on what is maximum perceived delay we can work to?
