I as hoping someone can shed some light as to why I am getting these errors in my console intermittently. This particular one happened during an attended Transfer. One party heard a horrible screeching noise so i check the console and this is what i could see

I realise I may need to provide some additional information but not sure what I should post.

Can anyone provide some assistance ??

Thanks.

Normally its down to codecs.
what codecs are enabled for thesets and peers

Using Alaw and Ulaw for all devices. They are the only allowed codecs in my sip.conf file.

This error only occurs when we transfer calls or park calls.

I can actually make it happen every time if I Park A Call -> Retrieve the Call From Park and then Park it again. As soon as I place the call on Park a Second time I get “static data transmission” noises on the line and I can see the errors on the console.

Can anyone provide any idea as to why this may be happening.
