Hello!
We have a particular fault at the moment due to a codec mismatch across some of our core trunks and our SIP cloud provider due to them changing their SBC dial-peer codec preferences.
We would like to amend this on our trunks to rectify the issue, but we would like to know if there is any way to courtesy down/wind down a trunk to it's secondary counterpart (our backup trunk), in order to not lose calls.
It is crucial we do not lose any calls in progress, therefore is this possible and if so, how?
Many Thanks!
