I have an Asterisk server (recent SVN version 1.2) and two Sipura ATAs
(one SPA2000 and one SPA1001).

I have Three-way Conf Serv and Three-way Call Serv enabled on both ATAs.

When I make a SIP call from phone 1 to phone 2 on my Asterisk box, it
works fine, then when I press the hookflash (TBR) on phone 1, the caller on
phone 2 is placed on hold (Asterisk MoH plays). I get the "second dial
tone" on the Sipura and dial another extension (phone 3) from phone 1
and it rings and I am connected. Now, if I press hookflash again on
phone 1, it switches the connection to phone 2, but phone 3 is placed on
hold rather than getting conferenced in.

Anyone got any idea why the three-way call might not be working in these
circumstances?

The message type for setting of Hookflash (none, AVT, INFO) seems to
make no difference. I normally set it to "none" as it should be handled
locally rather than get sent to Asterisk.

Thanks
Peter

I'm no expert, Peter, but I'm not sure that what you want to do is, in
fact, 3-way calling.
The 3-way seems to be working inasmuch as you can toggle between the 2
extensions.
Maybe what you want is conferencing?
