Trunks:
This sections will allow you to configure the trunks or outbound phone lines for your system. Analog Trunks or FXO ports are grouped together to simplify configuration, the default trunk group for FXO ports is "ZAP/G0". Analog trunks come pre-configured from Freevoice Telecom. To regenerate the FXO port configuration on the server login to the Linux CLI, for Digium cards use the command genzaptelconf, for Sangoma cards use the command setup-sangoma. VoIP trunks are configured according to the providers instructions. After these trunks have been built they must be set to be used by an outbound route.

General Settings

Outbound Caller ID - Send this caller ID number when calls are placed using this trunk. Only valid with certain PRI and VoIP providers.

Never Override Caller ID - Check this to keep the specified outbound caller id number, no matter what.

Maximum Channels - Set the maximum number of inbound and outbound calls for this trunk. If this Trunk contains four FXO ports set this to 4, for a PRI this should be set to 23. VoIP providers have different limits, contact your provider for their limit. We recommend VoIPStreet, they have a limit of 20 simultaneous call per account.

Outgoing Dial Rules

Dial Rules: These rules control how calls will be dialed on this trunk. These rules can be used to add or remove prefixes. Numbers dialed on this trunk that do not match any of these rules will be dialed as is. Use a '+' to add a prefix and a '|' to remove a prefix. For example for the rule '714|NXXXXXX', if '7143886015' was dialed on this trunk the '714' would be removed and only '3886015' would be dialed on the trunk. For the rule '1714+NXXXXXX', if '3886015' was dialed the prefix of '1714' would be added and the number would be dialed as '17143886015'.

Outbound Dial Prefix: Enter a prefix that will be added to numbers dialed out this trunk. This is useful if you have centrex analog lines that require a prefix of 9. To add a pause enter a 'w' for each second you would like to pause.
