[SR-Users] Re: Compatibility issue between proxy and registrar

Hello, in case you like to synchronize between 5.5.x and 5.7.x with DMQ – this is not recommended and in fact also not supported. You need to stay in one major version within a DMQ cluster (e.g. only 5.5.x or 5.7.x).

Kamailio proxy version 5.7.4 Kamailio registrar version: 5.5.5 Following the upgrade of the proxy server to 5.7.4, calls are not working and no response is received. Once again, we have reverted the proxy server to 5.5.5, so that the proxy server and the registrar server version are now the same.The calls are now working as expected. We suspect it could be an DMQ issue. I would appreciate your suggestions on this matter of compatibility between proxy and registry servers. Thanks.
