Hi all,

I have configure an SPA3102 to be used as a PSTN Gateway with a CX3 SIP server per

I do receive calls from PSTN to VOIP fine, but when trying the other way I get a "temporary unavailable". I hope someone can take a look and tell me if I'm missing something or if I should tweek some other parameters for this to work... I traced the SIP logs, and I get the following:

are you able to make any outbound calls over the SIP trunk at all?

Does your ISP allow outbound calls and are they expecting some sort of authentication from your side maybe?

It seems below with the message either there is really no lines available or you are not allowed to make outbound calls.

Call(C:1): from L:1.1[Extn:110]:

There are no available outbound lines on Trunk 'PSTNlineKrustyHouse' at this time

. First line: 10000

Hi Hermanus,

Not able to make any call at all.

There is no ISP,  I have this connected to my POTS line , which is not in use, so it should be available.

About the message, yeah I noticed it too, but again, the PSTN line is connected to my only POTS line. I do receive calls fine.
