IPSec IP Telephony:End to End or Segment
Hi,
I've a question which I hope the experts on
this list can answer/give their opinion.
With respect to IP Telephony, should security be
end-to-end or does it make sense to have it on
just one segment, eg between two IP Telephony Gateways.
Phone--PSTN--IPGW--IP Network--IPGW--PSTN-Phone
If security is only implemented between the Gateways
is the security risk unacceptable ??
If the phones were Internet-Phones, security could be
implemented end-to-end using IPSec, but what happens if
one end is an Internet Phone and one end is a normal PSTN Phone ?
