Step 2
Enter VoIP - Status page, wait one or two minutes (The time depends on SIP Server's
response speed and the network condition). When you see the Register Status is OK, the
registration is successful.
Figure 3-36. Status of Vigor 3300V
Note
Iptel SIP Server itself supports STUN function, so 3300V can register without STUN
enabled.
At present the above configuration has a precondition that Vigor 2600's VoIP isn't active.
If VoIP function is enabled, the packets on UDP 5060 will be received by Vigor 2600V
and not forwarded to Vigor 3300V. So you have to change Vigor 3300V's Local Port
from 5060 to 5061.
