Re: 3CX phone for iPhone 3G-incomplete registration CallCent
OK- Was able to get it to register. Now cannot complete test calls (Rings busy both outgoing and incoming). They suggest turning off MULTITASK and NAT; leaving STUN server blank; inserting callcentric.com as Proxy; I also tried substituting 5062 for local SIP port; they also suggest trying other apps another softphone provider. I also tried uninstall/reinstall of app.
Here's an excerpt from recent support ticket:

Your softphone is still sending the "loose routing" option. At this time, we suggest you contact 3CX for more information on how to disable loose routing.
As an alternative to the 3CX softphone, we recommend using either the iSip app (http://www.vnet-corp.com/iphone.htm) or Acrobits Softphone (http://www.acrobits.cz/products/acrobits-softphone/).
