Fallback to chan_sip SIP channel driver

Warning

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.

Note

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