Somebody use VPN to solve the VoIP Blocking issue. But it seems not a good way to solve the voip blocking issue. Because VPN will take more bandwidth and will take effection on the Voice Quality

Currently I am using the VGCP, a new solution to solve the VoIP Blocking issue. Following is theirs website:

If any of you have interested, you may try to use it to solve your VoIP Blocking problems. Thanks.

Originate dials ok but no DIALSTATUS
by simonInOz Tue 26 of Aug, 2008
Using the Manager interface, I issue an Originate command. It indeed dials, and is handled in the dialpan, but the DIALSTATUS value is empty (I have tried answered and unanswered calls).
I am using Trixbox 2.6.18-53.1.4.el5 (SMP)
Any idea why this is so? (How can I determine how the call went?)

exten => s,1,NoOp(HANGUPCAUSE is ${HANGUPCAUSE})

Cisco 7912G caught in a startup loop
by madturtle Mon 18 of Aug, 2008
Hello everyone,

I have a Cisco 7912G phone with SCCP ver 1.03 and I tried to load SIP 8.01 then SIP 1.01 via TFTP but it's not working. While I am able to go into the Network Configuration and specify the TFTP IP Address, IP Address and other functions when I save and reboot the phone it just goes off into an endless loop of searching for previous CallManager IP 10.24.97.1>Configuring VLAN>Configuring IP via DHCP> Repeat. The only thing that gets transferred via TFTP is the "gkdefault.cfg" file. I would see in status messages on the phone that TFTP times out even though the TFTP Address and, Laptop IP is correct and I turned off the firewall.

I previously read on this site I need to set the Profile Encrypt Key to "0" so the SIP firmware will auto load into the phone but when I go to Menu Key-> Settings-> Network Configuration -> The Profile Encrypt Key option doesn't exist.
