Zoiper 1.38 and Asterisk registration TLS+SRTP

Question

Hi All

I am not 100% sure but I think after upgrading to version 1.38 it is not possible to make any calls thru Asterisk anymore.

Right after making a call Asterisk instantly shows

    -- Unregistered SIP 'USERNAME'
    -- Registered SIP 'USERNAME' at SOME_IP:60771
    -- Unregistered SIP 'USERNAME'
    -- Registered SIP 'USERNAME' at SOME_IP:60771

and Zoiper times out with "Timeout(408)" doing nothing for 30 seconds or so and no message at Asterisk console.

I can send asterisk debug output (sip set debug ip ...) if requested.

Any clues are appreciated.

cheers

bb.

I have the exact same issue on two different Android devices.

Asterisk + TLS+ SRTP does not work anymore on version 1.38

Answer 1

We investigated this further and confirm there is a problem with the latest zoiper and the latest asterisk.

The issue seems to be that we now support more crypto methods and Asterisk does not seem to be able to handle the longer string with more crypto methods.

This might be the same bug as this one: https://issues.asterisk.org/jira/browse/ASTERISK-18345

If the patch there doesn't work, please open a new bug report for Asterisk.

Thanks for investigating!

Answer 2

Are you using Zoiper for Android?

Setup is:

Zoiper 1.3.8 for Android (Galaxy Note 4 - Android 6.0.1)

TLS+SRTP registering at Asterisk 11.7.0~dfsg-1ubuntu1

This setup is also not working with Zoiper 1.3.7 I use in another device (Galaxy S5).

So it is not 1.3.8 specific.

My configuration is the same: Asterisk 11.7.0 on Ubuntu server.

TLS+SRTP fails when dialing. Receiving calls works fine!

No problem dialing with UDP without SRTP.

Answer 3

I upgraded my Asterisk from version 11.7.0 to 13.10.0

Now everything works fine!
