[Asterisk-Users] SwissVoice IP10S can't take back call

[Daniel ANDRE]

Hello

I'm testing swissvoice IP10S with asterisk 0.7.1

When i place a call and hold it, i can't take back this call.
Asterisk seems to go into conference mode and i ve got a dialtone
instead of getting back the call.

Here is the asterisk output:

I have a look at chan_mgcp.c and it looks like asterisk thinks that
there are 2 active calls and decide to conference
instead of bringing up the only active call.

Does anyone use  this feature with mgcp? Does it work?
Is this a problem with asterisk (it seems so)?
or do i have to configure the phone to send something else than hf (hook
flashing) to take back the call? what sequence sould it send?

Thanks
