    Hello, 

    This could be due to a codec or RTP encryption used by the other party!

    Without phone settings and a SIP trace of the complete call, however, it is impossible to know!

    Mein Vorschläge sind: 

    1. It could be the case if the PBX doesn't support SRTP and the "RTP Encryption" on the phone is "ON".

      In this case: Please note that "RTP Encryption" is a per identity setting and needs to be disabled on all used identities under: Identity X -> RTP *(TAB) -> RTP Encryption

    2. Check the codec list on the phone and remove the Codec, that is not supported.  In some cases the use of codec G722 causes the mentioned issue!
