re: No VOIP for Panama Hi Dreamer,

I did read the boards on dslreports.com before I ordered the service a few months ago to see if Vonage was on the up-and-up. I just surfed there now, and I do see some complaints related to a service outage. So far I haven't been affected in NJ, though I did get an e-mail from them giving me a small rebate (I think it was $10 bucks) because of an outage.

In anycase, I have a cellphone for backup. I'm still a big fan of the service.

re: No VOIP for Panama Hi,
G.729 Voice over ATM over AAL2 = 28 cells per seconds = 11,872 bits per second and better QOS..

re: No VOIP for Panama For a space-fller topic like "No VoIP for Panama", this board is getting very contentious and cantankerous. I don't understand why there is such strongly held opinion on VoIP by Optical and IP guys, although I suspect it has to do with the fact that Voice over IP engineering requires knowledge of voice and IP, two skills rarely present in one person, and the fact that to implement VoIP in the WAN is difficult -- let no-one tell you otherwise -- and this does make JC look a little foolish with his comment -- build it for IP and voice travels for free...but I digress.

For one point of view with some facts and based on experience, look no further than:

Hi All,
Choose the first document in this search and you will see that you can get good QOS and lower bandwidth with VoATM over AAL2 than VoIP..
There is a table in the document showing the bandwidth usage with each option..

My comment:
Hmmm nice article, not bad actually. Just one thing though. Who makes a VoATM telephone set? Who makes Softphones that interface at ATM? Who makes Telephony application software that intergrates directly into the ATM later? I've only heard of VoIP sets! Which means if you wanna do Voice over Packet (the network could be enterprise or the Internet) and use these cool new IP sets you will need to do VoIP anyway. If your network is ATM based you will have to do VoIPoATM, and you end up wasting way more bandwidth than pure VoIP. I suppose you could keep buying those antique analog phones and use VoATM gateways. But half the fun is the cool features that come with the IP sets. Stuff like LDAP, DNS, HTTP/XML, MobileIP, IP Voice Mail, IP Auto-Attendant, IP Centrex, etc is all being incorpated into....you guessed it.....VoIP features. ATM is dead.

If you want to be able to take advantage of Voice over Packet in every way possible, pure VoIP end-to-end (ATM not needed) is the only way to go.

Yes I know there is little or no IP QoS on the public Internet today, but that is starting to change too.

If a carrier has a large deployment of ATM then I can see it making business sense, otherwise IP. Even some carriers who have large ATM networks are starting to announce a migration plan to IP only.

Can you elaborate on how the QoS is better in ATM? How is ATM QoS better than IP QoS? Please tell me.

re: No VOIP for Panama Hi PacketMan,
By the way, NTT DoCoMo 3G Phone is running VoIPoverATM AAL2..

re: No VOIP for Panama You're changing the subject ..... you kept telling us that VoATM QOS is better than VoIP QOS. I asked you who even makes VoATM applications, and I think I even said not VoIPoATM.

Regardless, cool phone ! Can you give me some WWW links as to where I can find more info on that phone? I am interested.

re: No VOIP for Panama " Can you elaborate on how the QoS is better in ATM? How is ATM QoS better than IP QoS? Please tell me. "

ATM has better QoS since it has cell tax,
otherwise ATM would have been dead long time
ago. Such cell tax is making ATM QoS predictable
in terms of traffic shaping,policing,bandwidth
calcaulation,jitter,latency control.....
all the mathematics.

whoever trys to do that will go bankrupt sooner than you can see the visible QoS public Internet......
There is no free lunch....
