i will like to add which sipura is possible to bridge voip to voip, is the
spa-3000 the only one and what about spa-2000.
in the case where i install spa3000 within an IPBX that does not support DISA and i need to bridge calls that is coming from PSTN through digium FXO card installed on the IPBX to my SPA3000 line1 and obtain a dialing tone to dial out using line2.
is this possible?
thanks
