I’m a newbie to SER but not VoIP and am having issues.  I have installed the latest SER from the website and am running with the default config.  I can have my sjphone clients register with for instance clientx@10.242.209.2 (the ip address of my SER).  Serctl ul show shows the clients as registered with proper ip addresses and information.  Attempting to call using with clientx or clientx@10.242.209.2 I get mkproxy: could not resolve name clientx then uri2proxy: bad hostname uri then tforward_nonack: failure to add branches.

Anyone identify what I did wrong?

Thanks
