3CX and VoIPfone outgoing calls

[paulwilde]

Hello, I wonder if somebody may be able to help
I have a test environment with 3CX set up with a basic VoIPfone.co.uk SIP trunk. I have incoming calls working fine, no problem at all, but when trying to call externally the 3cx phone just sounds the ringing sound but the called phone doesn't ring at all.
The error log shows
"Call or Registration to 0123456789@(Ln.10001@VoIPfone SIP Base Trunk) has failed. 1.2.3.4 replied: 603 No Funds; from IP:1.2.3.4:5060 " (phone numbers and IPs changed of course)
The clear bit is "603 No Funds", but I do have funds! Using VoIPfone's web client I am able to call externally fine.

Can anyone help? Or at the very least recommend a low cost SIP provider in the UK which is compatible with 3CX which I can use for testing?

Thanks

If the IP's you've changed are that of your provider (the message is coming from them), they you will have to contact them, for an explanation. The call is going to them, but they are rejecting it.

They are, so I will. Thanks.
I know they're a bit of a pain as they have their own cloud PBX so won't really help.
My own fault, should have gone with a supported SIP provider originally!

Going "supported" is always best if you want to avoid issues. The message "No Funds" seem pretty clear, so they should be able to explain that.

For future searchers with a similar problem, there's a simple fix here.
It turns out VoIPfone simply want the "From: User Part" to be your account number in the Outbound Parameters of your SIP trunk settings in 3CX.
Set this, and it works fine. You can also use

AccountNo*Ext i.e. 123456*200

if you use extensions

All good now, thanks!
