Hi Liviu,
I wasn't able to replicate your problem using updated versions of linphone from Linphone Desktop on Linux to Linphone Android.

It seems your ZRTP negotiation works as you're given the SAS and opportunity to set the verified flag but something may be wrong when writing the cache file as it is not even created (it should be even if you don't set the verified flag)

What OS your Linphone is running on?

Would you mind running the call with traces and sending them to me?

This is not a known problem at least. Did you make sure that both ends

validated ?

Yes, on multiple occasions. I'll check it again, just to make sure,
but thus far with 3.8.x I can't remember the ZRTP cache working right
a single time. I tried removing .linphone-zidcache on my end, and now
I realize that it has *never* been recreated, even if on several
occasions both users clicked on Verified. Can you replicate the issue
if you remove that file?

Thank you and regards,

PS My set-up is 3.8.5 (my machine) and 3.7.x (the other machine).

Best regards,

Dear devels,
In 3.7.x I never had issues with the ZRTP cache: once I verified this
with a caller on a given device, for the next call the ZRTP status was
automatically set to verified. In 3.8.5 it looks as if the ZRTP cache
is always corrupt: whether I hit verified or not, every call the ZRTP
status will default to "not verified".

Is this a regression in the 3.8.x branch?


Do you think you know what math is?
Or what it means to be intelligent?
