Netspectrum

Hi,

I have launched and running FusionPBX EC2 instance using the AMI from Netspectrum (at AWS Market Place). I'm using t2 micro with 30GB disk.

My purpose is :
1) Make a secure call using SRTP (end to end SRTP session)
I've already make some test using softphone (Linphone and Csip Simple for android), with enabling SRTP settings on both end point. The result is from the Active Calls Status(on FusionPBX Web-UI), the Caller Extension has already secure (there's SRTP crypto on the Secure column). But at the Receiver Extension, there's no SRTP crypto on the Secure column. Are those calls has been secured (end to end)?

2) Make a secure call using ZRTP (end to end ZRTP session)
I've already make some test using softphone (Linphone and Csip Simple for android), with enabling ZRTP settings on both end point. The result is from the Active Calls Status(on FusionPBX Web-UI), there's no ZRTP crypto on the Secure column for both Caller Extension and Receiver Extension. So I guest the ZRTP session (end to end) still did not works.

Any advise would be highly appreciated.

Thanks.

Hi, RG21,

Regarding your two questions, we at Netspectrum has not performed such configurations. So we don't know for sure how it could be achieved fusionpbx. I would encourage you to check in fusionpbx community and see if you can find any helps.

That said, freeswitch is certainly capable to support end-to-end SRTP and ZRTP connections. For example, see https://wiki.freeswitch.org/wiki/Secure_RTP and https://wiki.freeswitch.org/wiki/ZRTP .
