SIP external gateway only requires SIP TG if auth is none

[tiger]

My question is: a 3rd party/external sip server ABC/external sip gateway ABC connected to OXE. OXE is configured with SIP Trunk group with its SIP authentication is SIP None (not SIP digest). That External sip gateway ABC is not defined in OXE SIP external gateway i.e. OXE has no IP of this external gateway.

Can external sip gateway can call to OXE? Yes or NO?

If Yes, then OXE has settings that SIP external gateway ABC can use public trunks of OXE to make external calls to local, mobile, international Like trunk to trunk connection (connection category 5 have 5 allowed) and other settings are completely configured.

Can that SIP external gateway ABC after call to OXE use resources of OXE?

Regards
Tiger
