Still learning a lot.
I signed up for a CallCentric account, too see how it would work.
I am using a router w/ DD-WRT firmware, and I have QoS working pretty well. But I'm only making one call at a time.
The question I have is in regards to SIP. I'm I'm using a phone to make multiple simultaneous calls, are they all using 5060?
What if I'm using multiple phones, are they all talking on 5060?
My confusion stems from the fact that multiple people can browse or do ftp without altering the default ports. But I don't think this is true (necessarily) or SIP.
CallCentric said that for users making multiple calls, they have to open ports beyond 5060. I've attached their comment (below). But 3CX is only talking input (from the WAN) on 5060, no? Or is this a case where some sort of signal comes in on 5060, and the two sides agree to use 5061 or 5062?
How the heck does this work???

What ports do I need to use in my UA or firewall?
When configuring your user agent (UA) or firewall to work with Callcentric there are certain ports which need to be enabled to avoid quality and/or stability issues. Generally these ports are configured by default; however for users requiring the specific port numbers and protocols please use the information below:
NOTE: You can customize these ports however users who change the ports are generally doing this in advanced environments and will have access to the technical information required.
SIP Ports
Port = 5060
*Port range = 5060 - 5080
Protocol = UDP or UDP/TCP
Direction = Incoming and Outgoing
RTP Ports
The RTP port may vary by UA. If configuring a firewall you will want to configure a range which includes the default RTP port in your UA. A port range of 10 ports may work for most users.
If you will be placing multiple simultaneous calls then a larger range would be required. Users in this scenario will generally know their range requirements and should be able to implement this accordingly.
Port = Depends on UA
*Port range = Generally a range of 10 ports should suffice
Protocol = UDP or UDP/TCP
Direction = Incoming and Outgoing
*This is for users who may require a port range for their firewall or router

(Also 5090 for the tunnel). First simultaneous call would be 9000, second would be 9001 etc....
