Re: Mobile Applications (iOS & Android) Security
Hisha,

there are several options. Some of them are discussed in the v11 advanced training. I would recommend to either use H.460.17 based registration (H.323/TCP-TLS) or a separate front-end PBX with Session Border objects.

I will move this thread to the English Discussions section.

Re: Mobile Applications (iOS & Android) Security
Thanks Christoph.

What do you recommend if the mobile application only support SIP (3rd party applications we are using for iOS mobile phones)?

Re: Mobile Applications (iOS & Android) Security
I think this will be difficult anyway, as in this scenario, both the mobile phone and the peer (a local PBX extension for example) sit behind (different) NAT. So you could use SIP/TCP and do a port forwarding to the PBX (which is behind the NAT too), which will probably work. However, the RTP media channel will work only if your SIP phone on the mobile supports ICE/STUN, which i doubt it does (I have not yet seen such product before but I might of course be wrong).

If the RTP does not work due to this issue, I would recommend to use a frontend PBX with session border objects and you need to turn on media relay on the object for the SIP mobile user. That could work.

I have never done such a setup though, so these thoughts are pure paper-ware smile

Re: Mobile Applications (iOS & Android) Security
Hisham,

this is part of the v11 advanced training. Also, the overall idea is described in fish-help.png Hosting with V10. There are differences of course in V11 (forget about the media PBX in V11 (not needed by virtue of STUN/ICE)and use H.323/TLS instead of plain H.323) but the front-end idea is still the same.

Regards, Christoph
