<div><span style="font-family:arial,sans-serif;font-size:13px">Alex B may be right on this. Hard to speculate without hard evidence with lots of volume to back it up. I do know, however, that some carriers (Verizon comes to mind) will not support anything other than 20ms, so it is easier to standardize on a single ptime rather than try to customize each install.</span></div>

<div><span style="font-family:arial,sans-serif;font-size:13px">Are they suggesting SIP over TCP or some other out-of-band TCP to help manage quality to the endpoint. While we have a small amount of SIP/TCP going on to support older BLF integrations, I am not a fan. It adds overhead to the core (SBC) and also means that an SBC switch from active to standby will drop the device.</span></div>

At SIPNOC this week, we're having a "Birds of a Feather" session on delivering quality voice services across the public Internet.<br>
<br>
A few techniques to make voice across the Internet better:<br>
<br>
1. For packets from the ITSP to the customer: override the default BGP routing to choose an alternate route<br>
<br>
2. Increase the ptime from 20 ms to 30-40 ms to reduce packet-drop exposure<br>
<br>
3. EdgeWater brings us this one: actively manage TCP streams from Internet to CPE to provide better quality for Voice.<br>
<br>
So what OTHER techniques are there? Which techniques don't work?<br>
<br>
Yeah, it's the Internet. It's going to have failures. You're going to have bad days. But surely there are ways to improve the odds.<br>
