Устаревшие параметры файла sip.conf: incominglimit и outgoinglimit

Incominglimit = number of calls the local extension can originate to Asterisk.
Outgoinglimit = number of calls Asterisk will terminate to local extension.

End of Life for these commands announced, please use setgroup and checkgroup, that will also be helpful with cross channels. There is an example on how to do this at Asterisk cmd SetGroup.

It's from the viewpoint of the Asterisk PBX, not from the local extension.

The CLI command sip show inuse will show the current status.

Поддержка параметра outgoinglimit на данный момент отключена в исходных кодах SIP канала.
