[asterisk-users] 5-7 second connection delay in outgoing FXO calls

[Frank Tarczynski]

 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?
