Hi, the Alcatel OmniPCX Enterprise (OXE) of one of our customers seems to support the following encyption scenarios: - IP-phone on Alcatel OXE <=SRTP=> IP-phone on Alcatel OXE - IP-phone <=SIPS/SRTP=> Alcatel OXE <=> landline phone Unfortunately the Alcatel OXE doesn´t support SIPS/SRTP encryption betwenn itself and a SIP provider. So, for now it looks like: - Alcatel OXE <=SIP/RTP=> SIP provider The goal is, to encrypt that traffic, too. The SIP provider does support SRTP. So I´m asking myself whether to place a freeswitch between both which proxies and also encrypts the traffic? - Alcatel OXE <=SIP/STP> Freeswitch <=(SIPS)/SRTP=> SIP provider Has someone done something like this already? thanks in advance Michael
