Testing trunks


I have installed FREE PBX and have tested it using sip extension calls using two softphones.

I want to test some voip to PSTN calls. Is there anything like a test service provider so that I can test some VOIP to PSTN calls by creating a test trunk and dialing some simulated PSTN number.

Any help is much appreciated,

No but you can sign up for a pay as you go provider and just load the account with a few minutes.

Flowroute offers a pay as you go plan.
