Is it possible to pass an extension parameter to Freesitch like in Asterisk?

Question

Asterisk

In asterisk there is a wonderful opportunity to pass extension in register string for example like this
sip-id:[email protected]/extension
Does freeswitch have the same possibility? How many did not dig I can not find such a parameter.

Answer 1

in the gateway settings

<param name="extension" value="cluecon"/>
<param name="extension-in-contact" value="true"/>
