COS Options for SIP Trunking

[dogoferis]

Can anyone recomend appropriate COS options for programming a COS to be used with SIP trunks?  Any help would be greatly appreciated!

Thanks

With all the SIP trunks I have set-up there are always three extra options to set to yes. These are:

Public Network Access via DPNSS
Campon Tone Security/FAX Machine
Busy Override Security

Hope this helps
