Hi, I have an application where I need to be able to dial out to normal landlines and cell phones. I have a Sipphone account and am considering purchasing “Call Out” minutes from Sipphone. I’d appreciate any experiences people have had with calling out from asterisk over SIP and any info that would point me in the right direction. Thanks in advance.
It should be very simply. Just setup a SIP trunk to the service provider and setup a local SIP extension and then a dialplan to dial out to the SIP provider. Depending on how many concurrent calls you need to handling you may need to look at implementing QoS on your local network and setting some prioritisation on the Internet connection (if you can).
If you are new to Asterisk have a look at using AsteriskNOW or Trixbox as they will make the setup much easier.
