Hi and thanks for the reply. > Iam not sure about the PSTN thing. But u can use SMPP (short message peer to > peer) over kannel. it basically use TCP/IP conneciton to ur SMPP providers > network (SMSC) and from there u can route ur sms's. kannel supports SMPP > v.3.3 and v.3.4 > > KANNEL G/w-----tcp/ip-------> SMPP provider---->other SMSC's
So the first part of this I am to understand is that no one can really do this on their own, if you want to reach cell phones of a commercial network, you need to use a provider which can talk with that network, right? In other words, you can't be the provider unless you want to get into the phone business. The second thing is, which is more advantageous? Using a GSM modem or SMPP provider? Or perhaps a combination of both to do least cost routing? If using GSM modem, I would guess that I would need as many modems as I feel there would be simultaneous users, is this correct? If using SMPP, it's just over TCP/IP so nothing special, just access to the Internet. Also, if SMPP is peer-to-peer, does this mean you are relying on peers being in the areas that you think you will be communicating with? If so, then a GSM provider is wider coverage range? I don't know how many users we might have, we have some 2000+ customers but we don't know how many will want to use these SMS services yet. >Are u referring to Fixed line sms's ? iam not very sure about kannel. but >Asterisks suppport fixed line sms's I'm not sure, this is all new to me. I've started reading about SMS yesterday. I know that trixbox has SMS capability but so far, people seem to say avoid it, it's too rudimentary.
