IP termination using From tag.

Network endpoints

Use one of the following VoiceTel termination endpoints:

geo.voicetel.com
bgp.voicetel.com

Both endpoints are available for IP-authenticated outbound traffic. Test the endpoint that works best for the network path, routing behavior, PBX, SBC, and firewall configuration.

Caller ID and From tag requirements

Outbound traffic must include a supported caller ID header and the correct From tag.

Caller ID header

Use one of the following caller ID header types:

P-Asserted-Identity
Remote-Party-ID

From tag

The From tag must contain the account username. VoiceTel uses the username in the From tag to associate the outbound traffic with the correct account and approved IP address list.

Asterisk example

Example using account username 1234567890:

host=geo.voicetel.com
fromdomain=geo.voicetel.com
fromuser=1234567890
username=1234567890

; IP-authenticated termination should not use a registration line.
; Remove or comment out the register statement.
;register => 1234567890:PASSWORD@geo.voicetel.com:5060/1234567890~360

FreeSWITCH example

Example using account username 1234567890:

<param name="username" value="1234567890" />
<param name="from-user" value="1234567890" />
<param name="proxy" value="geo.voicetel.com" />
<param name="realm" value="geo.voicetel.com" />
<param name="register" value="false" />
