SX 80 unable to make outbound calls

[Ealey Seto]

Hello,

I have an SX 80 codec (TC7.3), no VCS servers or TMS.  The codec is currently registered to our CUCM (version 8.6.2).  It can make & receive calls within our company (basically any # within our CUCM).  However, it can only receive outside calls.  It cannot initiate calls outside our CUCM.  

It is setup as SIP.  We don't have a gatekeeper.  Is our CUCM version too old to handle external calls?  Do we need a VCS Edge server for external calls?

Thanks,

Ealey
