What exactly do you mean by "peered IP telephony"?
Voice telephony requires delays measured in tens of milliseconds. A bit difficult if you also want encryption, anonymity, etc.
The problem handling the delay comes with the network, not the encryption. The encryption can be symmetric, and must be used in a mode that tolerates drops, but its not a big cost when sending 8kbytes/sec.
