[asterisk-biz] DTMF duplicating

[AmberVoIP]

Let say, when ping is over 150ms, you have big chance for duplicates.
Also problem can cause echo cancelation (turn on and off and play with)
But i almost not seen duplicated DTMF with SIP on RFC2833.
And i never seen duplicated DTMF on IAX2.

So, if your POPs are far, just use asterisk and IAX2 channels between.
