Registry Settings

To remove restrictions on which adapters the VoIP will use: delete all DWORD values in HKLM\Comm\RTC\AdapterTypes

This will allow VoIP over your cellular radio and Wifi; but not on other available communication mediums, such as PC passthrough, bluetooth, etc. Unsure why this is. Restart of RTC stack is required (you can soft reset your device).

DWORD values named "1"-"8", should have the following values:
For CM_CONNTYPE_N the value is X...

• CM_CONNTYPE_UNKNOWN 0
• CM_CONNTYPE_CELLULAR 1 *working
• CM_CONNTYPE_NIC 2 *working (includes subtypes, like Wifi)
• CM_CONNTYPE_BLUETOOTH 3
• CM_CONNTYPE_UNIMODEM 4
• CM_CONNTYPE_VPN 5
• CM_CONNTYPE_PROXY 6
• CM_CONNTYPE_PC 7 *not working (this may be because of the double NAT transversal)

If you are successful, and calls are being dropped after 10-20 seconds, this DWORD value is a bug fix for NAT transversal: HKLM\Comm\RTC\NAT\ EnableEarlyUDPPackets dword:1

If you are having trouble connecting, you may need to specify that the SIP client can connect through port 5060 by changing the following DWORD value: HKLM\System\VoIP\SIP\ EnablePort5060 dword:1

Provisioning (eluth)

The provisioning (_setup.xml) settings are located in a file \Windows\System\VoIP titled ProvXSIPSettings (where X is a number). You need to delete this file to install a new _setup.xml provisioning CAB; otherwise the provisioning settings will not take.

Testing RTC Connection Mediums

* with no AdapterType restrictions
$ "Searching..." status may be reported, but testing has proven that SIP calling is available, even when "Searching..." is reported.
