    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!

    codec_priority_list


    Best regards

    Sidaty

    Thank you, where do i find the codecs in the telephone? So how can i delete the codecs from the webinterface? I don´t find any codec from the list: Supported Codecs on Snom Desk Phones


    So alle codecs with a red x i have to delete from the telefone?
