[asterisk-users] 5-7 second connection delay in outgoing FXO calls
I'm running AsteriskNow 1.7.1 with a OpenVox 2/FXO/2FXS card, a Linksys SPA942 SIP phone and outgoing SIP and IAX routes. When I dial local PSTN numbers from the SPA942 using the FXO channels I observe a 5-7 second delay between when the PSTN number answers the call and when Asterisk connects the call at my end. There's enough delay time that I hear an additional ring after the PSTN number has answered the call. I've had people hang-up since they don't hear anything when answering. If I try the exact same call using an IAX route, the call is connected at my end just as soon as the PSTN number answers. I don't have any connection delays for incomming FXO calls. They are connected as soon as I answer the calls. Can anyone give me some pointers on where to start looking? Frank

Changing it back to 80 made the problem go away.
