viop sip provider connection

Could you tell me possible or not to create SIP trunk to VOIP SIP provider (like SIPNET)? We have CM5.2 and SES.

Hi
its possible but you need to go through some admin steps first , please check the support.avaya.com website and review the administration manual for both the CM and session manager. you might need a session border controller ( SBC in short term = firewall for voice)

Is it possible to create SIP trunk w/o SBC? and use method SIP User Agent registration for this SIP trunk?
