RE: [Asterisk-Users] * + Codecs + Hardphones??
What about G.723.1? Anybody have any experiece with this? I know I can order the documentation (including C source) from the ITU, what does this entitle me to do? Are there any licencing gotcha's to going with this approach?

So far it seems that the Hardphones out there support G.711, G.729 and some times a few other codecs.. So the common denominator seems to be G.711, the problem with this codec is that it requires approx 64Kbps which is a little high for what I am trying to do.. So it looks like the best codec is the GSM codec as far and badwidth vs voice quality, but I can't seem to find which hard phones support the GSM codec or if * supports the G.729 codecs or others.. Which phones do the * user commumity find work the best?? and which codecs do you use?? G729 is currently not available due to patent and license issues. You will find that G711 is fine on a local network, and asterisk does real well using IAX protocol and GSM codec. So if you are deploying enough phones to make it worth while to drop a * machine on the LAN with the hardphones you are set. Otherwise you might want to look at the Snom phone since it supports GSM. -- Steven Critchfield [EMAIL PROTECTED] ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
RE: [Asterisk-Users] * + Codecs + Hardphones??
For $10 a pop, I would buy 24 to cover upto a T1 (and I've already got my call into Greg). This is exactly what I'm looking for. I suspect nothing bad would happen if you went over, except for that pang of guilt you may feel until you ante up for it's use :-) I'm personally more interested in the performance of the codec (ie what kind of raw power will I need to run it, how many can I run at once on a decently powered box etc...)

Quick question what happens if you go over your channel licenses?

The G.729 is currently considered beta.

[Asterisk-Users] Design Consideration
I've been looking at Asterisk now for several weeks and have had success using it with SIP based soft phones on a local network. I'm having some issues going to the next level (i.e. designing the system I want). Essentially this is what I want to do PSTN -PRI- Asterisk Satellite --- VoIP Gateway (i.e. Dlink) I would have many remote sites configured like this. From what I understand the Dlink can use the G.729e codec, but Asterisk cannot decode/encode that format to carry it over the PSTN. What options do I have that I can make this work or am I missing something obvious? What would you guys/gals do? Is anybody doing something similar? Preferred codecs, protocols, or hardware? I have a Voice over Frame technology working over satellite for several years and I'm looking for an IP based solutions (note I have got the VoFR technology working over IP but the price is prohibitive) Thanks in advance.
