UK Outbound Calls not working (Viper/VO-IP.co.uk/NumberPeople.co.uk)

[gotradesman]

Hi,
I am having problems getting outbound calls to work. When I dial a UK landline or mobile number from any phone/extension pair, I get "3CX cannot reach the number dialled" or "No oubound lines were available for this call".
My Trunk configuration appears to be connected (green square) however I am using a unsupported VOIP provider (Numberpeople.co.uk, who I think use vo-ip.co.uk)
I have been messing around with the outbound rules but to no avail. I'm not really sure what I'm doing with the oubound rules.

I have tried with and without dialling 9 before the UK number but just can't get it to work.

I was previously using an on-premise installation and had this working fine, but my 3cx trial licence expired so I switched over to SMB v20 and had to start from scratch.

I would really appreciate any assistance anyone can give with this.

NOTE: Inbound calls work perfectly.

Thanks so much.

Hi,

Was the old and new SIP Trunk provider the same? Using the same Outbound Rules?

Best,
K.

Hi K,
Yes exactly the same buddy. I'm baffled.

Can you screenshot the outbound rules? Second pair of eyes and all.

Surely there's a way of setting it up despite it not being officially supported. SIP is SIP right? I know there's a predefined list of providers to select when creating a trunk but most of them conform to the same set of config parameters so I have simply overwritten the prepopulated values to my providers details.
