<div>
<p class=MsoNormal>I am still on the early stages of the learning curve for
voip so pls bear with me. In regards to setting up SRST, I have read many
docs but I am still a little unclear on some design aspects, I was hoping
some experienced hands can share some knowledge. <o:p></o:p></p>

<div>
<p class=MsoNormal> <o:p></o:p></p>

<div>
<p class=MsoNormal>First basic question is, can SRST work when the local
'branch' router is either a VOIP GW or a regular transit router?<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>If yes and the router is a transit router will bear
bones SRST where PSTN is also directly connected to SRST router, what is
best/ norm practice in terms of when users want to make calls to the PSTN when
in fallback mode i.e. what number are presented to PSTN and also how are
inbound calls treated?<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I am thinking about a scenario where you have a DDI ranges
presented at remote PSTN hub sites that covers the remote site
running SRST. So from PSTN perspective all numbers with lets say 1xxx
would route via the hubs and the SRST site is 12xx. In the
scenario where WAN is down at remote, my understanding of SRST is that the
same DNs will register will the local SRST router i.e. the 12xx... However, I
am assuming the PSTN attached to the SRST router is another provider with a
different DDI, does this simply mean I have to do some translations to use
PSTN?<o:p></o:p></p>

<div>
<p class=MsoNormal>Also on the same sort of subject ! When integrating sites in
a CUCM clusters, trying to get some concrete reasons for not configuring the
sites with CME and running them as GWs to the cluster versus registering the
sites directly with one of the closest clusters; is there any scientific rules
for how far latency wise the cluster should be from end user phones ?<o:p></o:p></p>
