Outgoing call problem

[pwhayes]

Hi,

I am new to 3cx and have installed it and configured the connection to VOIPTalk and it all registers ok. Incoming calls are working fine but when I make an outgoing call I see:-

Extension goes orange and displays calling
VOIPCall icon goes orange and after a short delay shows ringing but cuts off straight away

The system log shows:-

Incoming call from extension 100 to siphonenumber@server ip
Line 10000@VoipTalk is ringing
Call from Ext.100 to phonenumber terminated; cause: 503 Service Unavailable; from IP:217.14.132.183

Does anyone know what I am missing?

You will need to provide more details. Please read http://www.3cx.com/forums/viewtopic.php?t=93 also. On the presumption that you are in the UK and using https://www.voiptalk.org my first suggestion is they apparently use port 5065 compared to 3CX default 5060, did you reconfigure correctly including firewall and/or port forwarding as needed?

Good evening

Have you tried bypassing 3CX by calling with a softphone like X-Lite registered directly to the VoIP account?

If the problem persists when calling from the softphone you know it is most likely not a 3CX setting but more likely something on the network or at the VoIP provider.

You may also want to double check your firewall/router to ensure you have the appropriate ports opened up for traffic both directions.

At one point I was having trouble getting a VoIP provider to work and after alot of calls discovered that the gateway had a small routine that needed to be disabled in order for the VoIP provider to work so don't rule out calling your router/firewall manufacturer :shock:

Thank you both. I have just found the problem and it was predictably obvious. In the outgoing rule I had missed the default setting that strips the first character off of the telephone number. So everything I was dialling was a wrong number?
