Reply(200OK) that comes from PSTN is:Ī=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:SuPHLA6YgrTfVYL0jGiQiQToEtWFdjCXPvAQyxuj|2^31


My SBC forwards this to PSTN with PCMA and telephone-event 8khz. what happens actually is in order of precedence(removed unnecessary lines):ĬALL-ID: f642931530e0550ea9f08efab72d7927

And actually I see the where it is and only way for me to fix is to downgrade the call from SILK 16khz to 8khz.
