try to get a clear picture on how to set up Sv9100 to TWC cable sip trunk, TWC send me the sip information to fill out, indicated the ESG gateway to PBX connection is WAN,IP address is 172.16.x.x.255.xxx.xxx.xxx.my question is on the 9100 what need to be assign to 10-12-09 and 84-26.10-23? do I need to a Router in between TWC ESG gateway ?

Thanks.

Johnny,

We deal with TWC all of the time. Need to have TWC set a local LAN IP Address and subnet on their ESG. Then on the SV9100 the SIP Trunk will communicate to this LAN IP. NTAC has a cheetsheat on this re: TWC.

Thanks to nec-guru,
I got the cheat sheet from NTAC but still not clear, it talks about may needs to do Port Forwarding?
1.Do I need to need to do it?
2.tell TWC to change the ESG hand out to PBX from WAN to LAN ? I need two LAN Port.
3.what I need to assigned to 10-23 IP address?

Thank you very much.
