This is caused by a limitation in the sip2sip.info prepaid service. Using a prepaid balance only one call can be made to PSTN at the time. 

If you open a ticket at sip2sip with a request to increase this limit, it can be solved.

Well, a VPN means you are behind a network that has a firewall of some sort.  They may be blocking SIP all together. You can check the SIP logs if you get any replies back or not.

Does other SIP client work in that environment?
