SIP Trunk to Service Provider

[NinjaUK51]

Hi,

We have a S8720 running CM5 with G650 PN's (C-LAN's, Medpro's, etc) and we would like to connect a SIP trunk into our telco.

Our techy guy at the telco has said that we would actually be connecting into their Session Border Controller (which is an ACME Packet Net-Net) and then breaking out of their PSTN gateways.

I have checked in CM and it looks like I can create a SIP signalling group and can change TLS to TCP (which I have been told I need to do).

My question is "do I still need an SES Server?"
I am getting some conflicting information back from our Avaya account team on this, so any help would be greatly appreciated.

Cheers,

Ninja

Yes, you still need a SIP Server. Your Signal Group is actually between the S8720 CLAN and the SES. Then the SES does the interface to the ACME Packet Session Border Controller. I'm doing the same thing here in the states with two customers running S8720's at release 4, with S8500 SIP Servers interfacing to ACME Packet SBC's. SIP is only native to the S8300 in Release 5, if I recall correctly.
