https://github.com/istio/istio/issues/36301#issuecomment-983413360 可以试下这个方式，需要先安装 istio crd，并开启 higress 的 istio api 支持，可以参考：https://higress.io/zh-cn/docs/ops/deploy-by-helm#%E6%94%AF%E6%8C%81-istio-crd%E5%8F%AF%E9%80%89

@chaoyoung 试一下这个enovyfilter ```yaml apiVersion: networking.istio.io/v1alpha3 kind: EnvoyFilter metadata: name: enable-secp384r1 spec: configPatches: - applyTo: CLUSTER match: cluster: # 例如 service: foobar.default.svc.cluster.local service: context: GATEWAY patch: operation: MERGE value: transport_socket: name:...

@chaoyoung 可以提供下 freeswitch-uas 这个服务的镜像吗，我这边测试复现下

@chaoyoung 抱歉 这段时间比较忙 还没来得及复现问题，你先试一下这个envoyfilter能否解决 ```yaml apiVersion: networking.istio.io/v1alpha3 kind: EnvoyFilter metadata: name: freeswitch-uas-enable-secp384r1 namespace: default spec: configPatches: - applyTo: CLUSTER match: cluster: service: freeswitch-uas.default.svc.cluster.local context: GATEWAY patch: operation: MERGE value: transport_socket:...

你进网关的pod 执行下 curl localhost:15000/config_dump ，把内容发一下

 你的配置中只有这些服务，并没有 freeswitch-uas.default.svc.cluster.local，所以上面的envoyfilter没有生效

 envoyfilter 的 patch 看上去没有生效，你看下 gateway 的 pod 日志，有没有报错信息

@chaoyoung 默认支持 v1.2 的
