[Asterisk-Users] Asterisk (g729) termination on CISCO

[Roman]

Hello All,

I looked at the codec supplied by Digium and I think that 
it is G.729 Annex-B (G.729b - 8kbps). Correct me if I'm 
wrong. I have also looked at the article from Cisco "VOIP 
Understanding Codecs: Complexity, Hardware Support, MOS, 
and Negotiation", which states that G.729b is supported on 
pretty much everything except for AS5350/5400. Also that 
G.729b is a "high complexity" codec that will require 
twice the DSP processing. Now given all of that, has 
anyone interoperated Digium (E1(4)00P, T1(4)00P) -> 
Asterisk (g729b) -> CISCO termination -> PSTN. This whole 
setup is for purposes of VoIP. How inter-operatable is 
VoiceAge's codec with cisco's version of it?

Also in the short description of G729 on the Digium's 
site, they state that "Dual Intel? Xeon 1.8GHz processors 
allowed 60 concurrent calls". * seems to be multithreaded, 
so anyone tried dual-AMD mobos for that? What kind of 
setup would one then need to work E400P (total of 120 
channels + G729)?

Looking forward to hearing from you.
Thanks, Roman
