Hi,
I am an ASTERISK expert not just using or installing it - I work with the code and electronics. I am an expert programmer, electronics, hardware, VOIP/GSM/RF/PSTN/SAT, etc.
I developed my own g729 codec to be used with Asterisk.
If you just want to fool Asterisk into believing it has speex then it can be done but it may require changing the code of asterisk. For this you need a coding expert.
I am a Canadian Technology develop and a registered Canadian business. I dont do ESCROW so you will need to pay the advance payment via PayPal or interac.
Thank you.
Warm regards,
Anthonus.
