<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Is
there any mechanism to ‘speed up’ skinny call setup like faststart
in h323? Satellite provider migrated to skinny gateways (SCCP controlled FXS
ports) from h323 gateways. All analog phones. It was noticed that
inbound PSTN calls (through h323 gateway) were losing the first second or so of
the call when the called party picked up. This made sense to me as the
skinny gateway must tell CM the phone has gone offhook then CM tells the gateway
to tell the phone to stop ringing and send media stream to the PSTN
gateway. This is over a 600-700ms satellite link so the delay would be
reasonable. The rest of the call is perfect. If the same skinny
gateway is changed to h323 the delay is not present since h323 gets the IP
address where to send the stream during call setup if I’m not mistaken so
the delay isn’t present, but neither are the features of skinny controlled
fxs ports…<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>To
me this is all reasonable and makes perfect sense. The question the customer
has is if there is any mechanism to speed up the skinny signaling. I wouldn’t
think so based on the master/slave nature of the skinny protocol. I’ve
configured voice call send-alert, voice rtp send-recv, progress_ind setup
enable 3, and all that, but nothing helps and I can understand why.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Can
anyone confirm if there is a way to speed up skinny call setup over high
latency links? Running CM 7.0, SCCP controlled FXS.<o:p></o:p></span></p>
