We are in the process of using IP phones in our india office and currently have a 256K circuit in place. What we are trying to find out is, if the circuit goes down how can we route our voice traffic over the PSTN. Or if the traffic is reaching a certain point on that circuit, how do we reroute IP phone traffic over the PSTN.
If your india office is a remote office and the ip phones registered to a CCM at central site then you can make use of SRST feature. In that case when the ip link goes down the router would act as a mini CCM and the phones would register to it and use the PSTN line off of the Gateway to make calls out. More can be found on the following URL:
Thanks for the info, but what we have found out is, If you have a router connected in India to a circuit from the USA, you cannot have a gateway in the India router connected to the India PSTN. We have found a few regulations that prohibit any circuits being connected to there PSTN. At first, adding SRST was our first thought, then we were stopped by this regulation.
So, if I'm not mistaken, this is not about IP Telephony, but alternative IP connectivity issues (in order to keep your VoIP, up-n-running)... Well, do local lows also prohibit satelite connections ? There are small, portable satelite-dish devices, which are IP-enabled, and offer ISDN speeds (and sometimes, time-usage based, rates). This does not have to be a too expensive solution. It all depends on what you want to do, and how important it is for your company. Well, it also depends on (local or at least close-by) providers too...
About the regulation, if a router in India has a LAN connection to another Router in India that has a WAN connection to the US, is that still considered a regulation? If this regulation has been there for quite some time, I wonder how the telecommunication companies are providing such cheap rates to India (which indeed uses the VoIP Technology).
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
