[SIPForum-discussion] IPSec-SIP integration

[Thomas Lentz]

Hi Dhar,
the IPSEC security idea for IMS is probably as old as the first IMS idea. 
The (internet) world has gone a different way (SIP over TLS and SRTP). If 
I can't hold you back to break your neck with IPSec (it just doesn't scale 
for carrier platforms) you can try the Mercuro client. This client is the 
most advanced IMS client I came across, before abondonning interest in the 
mobile carriers' SIP fantasy (IMS).
Unfortunately it seems the project hasn't paid of, so they stopped the 
development 2 years ago - but I still use it to verify IMS functions of 
our platform.

Hello Everyone, 

For our project requirement, i was researching on integration of 
ipsec(strongswan) and sip(pjsip) for simulating a IMS VoLTE client.
1.) Can anyone assure me that if i add the required headers for ipsec 
negotiation in SIP messages and configure IP/port combinations, algorithms 
in 
     ipsec(strongswan) i would be able to make a sip call over ipsec?
2.) If not, what it would take to make it work?
3.) Are there any opensource/commercial sip softclients which support 
ipsec?

Thanks,
Dhar.
