Hello All,
I was wondering if somebody could elaborate the change in
translation of codecs specifically the amount of time increased in Asterisk
11. For example
*Asterisk 11*
* **alaw **speex *
*gsm **15000 **15000 *
*ulaw 9150 15000*
* *
*Asterisk 1.6.x*
* **alaw **speex *
*gsm **2 12002 *
*ulaw 1 12002*
I did recalculate the translation for 60 or 1 seconds but nothing changes
on Asterisk 11 (VM, Cloud or even physical machine). Is it slin?, adding
this overhead or there is something I am overlooking?.
