SIP Trunk on CM7... Can it be done?

[snajo]

We have an Avaya 8710 running CM7. We want to ditch a PRI circuit and switch to SIP trunking. The switch is IP capable. We have have an IPSI installed and running VoIP through the switch. Can it handle SIP trunks? I hope I gave enough information as I don't know what is needed for a SIP trunk yet. Thanks.

Sure, you'll just need an SBC to interface between the SIP provider and your SM or CM.

But it would technically work with out an SBC, correct?

Highly unlikely and you would never want to do that anyway.

Before you get too far down the road, check to make sure you have SIP trunk licenses in system-parameters customer-options. With that said, you have received some wise counsel to not expose your switch to your provider's SBC. You really should have System and Session managers and your own SBC. Without them you will be limited on what you can manipulate in your SIP traffic and will be trusting your provider to protect you. You might also struggle during initial setup and future troubleshooting because of CM's list trace feature not being as good as ASM's traceSM/traceSBC. If all of the above aligns for you, there's no other technical reason it won't work.

We're all ignorant, just in different subjects.

Thank you both for the info!
