Seem strnage you have no parameters for vbr-nrt. You should have SCR and MBS.

I recall there's a general guideline for bandwidth less than 768 you'll need something like LFI because of serialization delays caused by large packets. Not sure such is easily availble with ATM, so you'll probably need to have another PVC defined and dedicated to your voice, ideally a cbr or vbr-rt PVC.

i think problem was solved with adjusting tx-ring limit as 4 part.Now voice packets arrives more efficiently.Ä° asked telco that we used to vbr-rt and encapsulation is aal5snap.
Thanks for advices
