How to filter the dialplan so that you can see all rows by extension?

Question

Asterisk

For example:
mynumber => 1. Dial(SIP/${EXTEN} router ,,Tt) [pbx_config]
2. HangUp() [pbx_config]
And display 2 lines at once through “dialplan show | grep mynumber" fails.

Answer 1

dial plan show | grep -C2 mynumber
if mynumber can have an arbitrary number of lines, not 2, it's easier to write a perl script.
