hey guys,

                    have just finished setting up an SPA9000 and SPA400 as PSTN gateway, ISTP works perfectly, but PSTN drops xfer.

Xfer between internal phones tests ok...

Hi Matt,

what are the firmwares being currently used in the system devices?

When you are performing the transfer to the external line is it a blind xfer or do you let it ring on your phone before completing the xfer? The version of firmware would be very useful as well. I have tested this in my lab environment and it works every time.

the firmwares are as follows,

SPA-942 Phones: 5.1.5a

SPA-9000 : 6.1.5

SPA-400 :

and it does allow me to call befoe the xfer is complete so i am assuming this is not a blind xfer

i have also noticed that i CANNOT dial the internal extension numbers, the handsets tell me that its an invalid number...

thanks for the input sofar guys.

Use the setup wizard to upgrade the phone software  as well  and then come back if the Xfer is not working

Hi Matt,

Does the fact that the spa942 phone had older software on it indicate that you did not use the new  configuration wizard to configure this system ?

if you have not got the wizard already, go to the following URL. Underneath the picture of the spa9000 is a 'download software" button, grab the wizard after signing in..

You must be able to call another spa942 on the LAN,  if you find that the configuration wizard does not fix your problem, then best to talk to the folks at the Small Business Support center.

What follows is a link to contact numbers in your country;

regards Dave
