VoIP Proxy

SIP_PHONE-1<--->Cisco<--->SIP_PHONE-2

I have IOS c2800nm-ipvoice-mz.124-15.T1. How I can to transparently transmit a SIP connection through this cisco, without of changing of SIP_PHONE-1 address to the adress of Cisco ?

Re: VoIP Proxy

• Session Initiation Protocol (SIP) v2 (RFC 3261, 3262, 3263, 3264)

• SIP proxy redundancy - dynamic via DNS SRV, A records deregistration with primary SIP proxy server

• SIP support in network address translation (NAT) networks (including Serial Tunnel [STUN])

• Highly secure (encrypted) calling via prestandard implementation of Secure RTP

• Codec name assignment
