[eng]: does it forward PSTN-to-VoIP without going hook-off?

[tommmy.leee]

hello,

sorry for writing english in here

i would like to use Asterisk as the base call triggering device and let ANA (SPA-3000) work only as a gateway for incoming from PSTN calls.

does anyone know if this possible to configure ANA so that it does not create the PSTN call leg (does not answer to incoming PSTN call) but sends INVITEs immediately?

more precise:

if configured so (as "hotline"), SPA-3000 does the following:

1.answers the call on PSTN (makes off-hook)
2.dials in the assigned for forwarding VoIP address (sends INVITE message)

step #1 creates PSTN call leg for the caller (what is not right in
case if VoIP address not answering, then caller will be billed for
this), is there a way (for such "hotline") to avoid picking up the
call (step#1) completely (so if the PSTN line ringing, then only
step#2 performed; only in case if the VoIP address is answering the
call, then SPA goes off-hook on PSTN line)?

thanks,

tommmy.leee

Hi,

it's been a while ago since I have been using and configuring the SPA-3000, but I am quite sure that the scenario you desribe is not possible (yet).

thanks for the answering. actually googling does its job:

http://www.voip-info.org/tiki-print.php?page=Sipura+3000

but it is just a workaround... i think everybody who owns this device would be happy to have such a feature just in the firmware.

look at my mailng with sipura support guys below, maybe if somebody else writes on them willing the same then they turn out to implement it with next release of its firmware...

hello again,

what a pity. nevertheless, thank you very much for all your time you
spend answering me.

by the way, this feature is desired by many others, not only me.
people found a work around to do so BUT it does not work in 100%
cases, so maybe there is a possibility to implement it in the
firmware...

take a look here
http://www.voip-info.org/tiki-print.php?page=Sipura+3000

would be nice if you take this one as the wish from your faithful customers.

thank you so much again!

with best regards,
tommmy leee
