SRST with both SCCP and SIP phones

Interesting observation here.

I have SCCP and SIP phones both registering great in SRST, but noticed that SIP-SCCP internal calling comes into the SCCP phone as an external call.  For instance

SCCP DN: 234035 calls SIP DN: 234071.  Call rings as double-ring and the calling party ID is presented as my translated 2128984035.

SIP DN: 234071 calls SCCP DN: 234035.   Call rings as single-ring and the calling party ID is presented as 234071.

I know in SRST this is like two phone systems, so to speak.  My SIP ephone DN dial-peers register as voip and my SCCP ephone DN dial-peers register as pots.

Is this behavior normal?  It’s just confusing to have on-net calls ring as external.
