Brendan Martens commented on ASTERISK-19871:
--------------------------------------------

What is the situation for getting this fixed? It dramatically reduces the usefulness of silk... I am a bit confused why silk was added if it was just going to be left in a crippled state?

> Hi ,
> We are facing new issue that we create two users with enabled codec SILK24 and SILK8, when we calling to user1(SILK24) from user2(SILK8) we got the messages in Asterisk Console like this
>  
> [May 14 16:17:35] WARNING[16123] chan_sip.c: Asked to transmit frame type silk8, while native formats is (silk24) read/write = silk8/silk8
> [May 14 16:22:11] WARNING[15914] channel.c: Unable to find a codec translation path from (silk24) to (silk8)
> This messages continuously running until we hanged up the call .
> But It is working fine with other codecs For example I can make the outgoing calls through my SIP provider (ULAW) and other codecs also
> Working Scenarios:
>  SILK8 - ULAW,ilbc,gsm..
>  SILK8 - SILK8 
> Not Working
>  SILK8 <-> SILK(16,24)
>  
> Here is the table value that we got running Asterisk CLI command # core show translations.
