Hi,
Sorry if I missed any developments on this, but:
Kamailio does keep a runtime association of Call-ID+Ftag => RTPEngine instance, which is significant if an RTPEngine set with multiple members is used, or if a non-default set is used for a given call.
When Kamailio is restarted, this runtime association goes away, so any subsequent offer/answer cycles or any other commands will (maybe) go to the wrong RTPEngine and/or the wrong set.
Last time I checked a few years ago, there was no way to persist this association across restarts. Has this changed?
Thanks!
