I forward Google voice to both IPKALL and Gizmo5, and then to sipsorcery. I can call out without problem but can not receive phone calls. At sipsorcery i saw my ATA there ( myusername@myipaddress). In the callout dialplan i put my IPKALL number, the funny thing is if i dial my IPKALL number directly i always got busy tone. I also tried to use a softphone "Express Talk" but can't even register with sipsorcery.com. Can anyone let me know what the problem might be. Any suggestion will be appreciated. Thx.
Update: The problem is gone after i change the SIP account name to my username at Sipsorcery i guess. I'm not sure if i can create additional account with the name of 001-rnapolean or 001_rnapolean, that will be very convenient.
