SIP/IOS integration?

[Nolan Darilek]

I'm evaluating web RTC gateways for a project I hope to roll out soon.
The mobile web is my primary platform, but my hope is to target both IOS
and Android. Unfortunately, since web RTC isn't supported on IOS, and
since I'm neither an IOS developer nor do I have the resources to hire
one, trying to make something work is proving challenging.

My current thoughts are to use Kurento and to build a SIP servlet which
IOS users access via a native SIP client. Since this space is rapidly
evolving, I've been evaluating Kurento-like solutions and recently
discovered Janus.

Has anyone done a Janus->IOS integration that lets IOS clients
send/receive calls to a Janus gateway? Failing that, is there a good,
lightweight SIP integration that plays well with Janus? I want all of
the logic to be handled by my web app; it just calls into Janus to
coordinate comms, and the SIP integration authenticates against my
app/database and streams calls through Janus if a SIP user calls an RTC
user or vice versa. I spent months trying to figure out how to make
Asterisk/Freeswitch delegate authentication to an API call rather than
handling them in their own databases and came up short, and Kamailio's
custom programming language is a pain to learn, so it seems like all of
those would be overkill.

Thanks.

Have you tried Ericsson's Bowser (iOS browser with webrtc support) from the Apple Store?  I tried it with the videoroom plugin without success some time ago, but it has been updated since.
