Asterisk & SIP

Asterisk default SIP channel driver is since XiVO Izar PJSIP.

Fallback to chan_sip SIP channel driver


If you chose to fallback to chan_sip you will need to redo it for each bugfix upgrade.

For Izar LTS a fallback mechanism has been implemented to be able to fallback to deprecated chan_sip SIP channel driver.

On your XiVO, run the following command to switch your XiVO from res_pjsip to chan_sip:

xivo-switch-sip-driver SIP

And follow the instructions displayed.


If you’re running an XDS installation you MUST switch all the XiVO and MDS of the installation to the same SIP channel driver.
