Open Source SIP Clients
-
SIP, like HTTP, FTP, XMPP, SMTP is not encrypted. SSL encryption is at a different layer. So SIP traffic is often quite secure. But SIP itself doesn't do the encryption.
-
I remember hearing good things about Jitsi (not specifically on Linux but in general) but have not tried it.
-
Just installed Blink. Trying it out today.

What exactly would you use this for? when you're traveling so you can connect directly to a SIP trunk? instead of connecting to your office PBX?
Am I mistaken in thinking that a SIP line is nothing more than an IP based POTS line? (OK it can do a ton more, but you see where I'm going with this)...

@Dashrender Most PBXs will do IM/Chat voice and some video.
But, SIP doesn't just mean IP Phone systems sip is a connection type http://en.wikipedia.org/wiki/Session_Initiation_Protocol -
I wish someone would make a fully featured Lync open source alternative. Lync is great but it's so dang expensive for what it is. IIRC it's more than exhcnage is with CALS and all. Openfire is close but it lacks some features and needs more native SSO support that well, actually works.

This is my phone. SIP is what you use to connect to the PBX. A soft phone doesn't bypass the PBX. It's just what you can choose instead of a phone on your desk.

Which Lync features do you seek?

No, SIP is nothing more than a delivery method for phone service. It does not even mean you have an inbound phone number (DID).

Scott stated how he is using it, but you can use a SIP compatible client to connect directly to a provider also. Technically there is not much difference between a SIP trunk and a SIP connection from a phone (desk or soft) because well, it is SIP. SIP is a standard protocol.
At home I have a Yealink T38G, a Yealink T42G, and an Obi100. The phones talk to PBX systems. The Obi talks to VoIP.ms. I could use the phones to talk directly to VoIP.ms also and just get rid of the Obi100, but it is connected to a cordless phone and I have not gotten around to it yet. The Obi100 does not have a DID. it is used ONLY for outbound calling at home. Generally only for my wife to call her family in Japan. I use it occasionally to test inbound call routing for other systems.

Thanks guys, I missed the fact that this was a 'soft phone'
