My client is considering a IPT deployment using call manager, theyt are an education authority and have look after a large number of schools.
There is a need to provide survivable comms in the event of a network outage, but the difference is, as these are schools we need survivable comms to work inbound so that parents can still ring in.. I am considering deployiong a small CPE as a voice gateway at each school to cope with this, so my question is will SRST work inbound so that parents can call in even in the event of an outage..?
one the router is still up and srst is working calls can go bothways locally. i have it setup as plar connections in the event of a WAN failure. so if someone calls in, it goes directly to that phone, if that phone doesnt answer, i have aliases, CFNA and CFB, setup to hunt through to identified phones until the call is answered.
If the PSTN services for that site (T1s, Analogs, Etc) is terminated on the gateway that will provide srst then inbound calls can be connected. The design is dependent on the model you are using. If you have multiple sites then you should have PSTN services terminated at each site. When the site looses network connectivity and fails over to the local SRST router then the PSTN services are still accesable. Note:If you are using MGCP then you also need MGCP to fall back to H.323 otherwise your MGCP interfaces will not work.
