This should be a valid FreeSWITCH ™ dialstring.
Examples can be found at
the FreeSWITCH™ wiki.
$1 is replaced by the number to be dialed, you probably want to ignore early media.
Some simple examples:
- Dial by gateway: {ignore_early_media=true}sofia/gateway/example.com/$1
- Dial by profile {ignore_early_media=true}sofia/mydomain.com/$1
- Forked dial: {ignore_early_media=true}sofia/gateway/example.com/$1,sofia/gateway/otherexample.com/$1
- Failover dial: {ignore_early_media=true}sofia/gateway/example.com/$1|sofia/gateway/otherexample.com/$1
- OpenZap dial: {ignore_early_media}openzap/1/a/$1
Please read the relevant documentation to determine what your dial string should be. This dialstring is used whenever an 'external' number has to be called - outbound calls, warm transfers, agents on a PSTN line, etc.
