i have now managed to get all my stuff working using sr except t_uac_dlg. t_uac_dlg is not working because for some reason sr tm module does not implement t_uac_dlg and mi_rpc tells "async mi cmd not implemented yet".
i would prefer native support of t_uac_dlg in tm module, because the idea was that sr will use ser tm module. if t_uac is difficult to implement in ser tm module or if that would still not make t_uac_dlg to work via rpc, then i guess i need to wait until mi_rpc supports async mi functions.
otherwise things thus look pretty good to me. thanks for your efforts.
