I have a weird problem with some installations that i have done, some Elastix 2.0.3 and some PIAF (latest version with Asterisk 1.. Every time that i make a change in the Asterisk and make a reload the phone that i have connected on the FXS rings back and from the system i see that the one that makes the call is the extension that i have configured for this specific fxs. If you have any recomendations, please respond.
