PSTN Outbound and VOIP Inbound/Outbound

Asterisk Asterisk Support
1

I recently installed asterisk for a demo and want to showcase inbound/outbound PSTN and inbound/outbound VOIP. I’m using the SPA400 as my FXO port and varphonex as my VOIP ITSP. I’m able to make inbound PSTN calls with no problems. When I try to setup outbound PSTN, it seems to be send something invalid to the SPA400. I believe it is not stripping the preceeding 9 or something. In either case, I get a circuit-busy, congestion message. I haven’t even tried VOIP other than succesfully registering a peer. If anyone can help in that space, it would be great. My sip.conf and extensions.conf are as follows:

Please help.

I probably should double check that the :1 shouldn't be :2 and that you aren't required to use the trailing / variation.

David55… thanks that worked like a charm. My only problem now is I’m getting no sound on either end. I can answer, but hear nothing. Any thoughts? Thanks again!
