Hello, while configuring SRTP i faced problem with Zoiper SIP client, when i'm trying to call someone i'm getting this message in MyPBX console:
Unsupported crypto suite: AES_256_CM_HMAC_SHA1_80
By the way, when i'm calling to Zoiper SIP client everything alright and works perfect. How can i make it work, how can i make this crypto suite be supported?
The SRTP required both side support. So if you only enable SRTP on the PBX or only on the Zoiper, then probably it will not work.
Check if you enable both end the SRTP or not. I am using an old version of Zoiper and couldn't found a SRTP setting. Not sure if newer version supports.
I double-checked it, SRTP configured for both sides (i'm using Android Zoiper version). I think there is a crypto suite version conflict. When i making call via Zoiper, Zoiper offers AES_256_CM_HMAC_SHA1_80 connection to PBX and PBX refuse it. But when i making call via stationary sip phone everything goes alright, because PBX offers Zoiper another crypto suit wich Zoiper understands and accepts.
The question is how to make MyPBX understand AES_256_CM_HMAC_SHA1_80.
Fidemdisp,
I test with Yealink T27P with SRTP and it works, I found Yealink use AES 128. So I guess Yeastar doesn't support SRTP wiht AES 256. See below screenshot:
Understood, thank you a lot!!
Microsoft Teams Integration
Hikvision Intercom Integration
ISDN Switch-off Migration
All materials to evaluate Yeastar as a PBX vendor on products, solutions, partner program, support, learning resources, etc.
