Hey does anyone know if it is possible, and what I need to buy and configure to trunk either a Cisco UC520 system or a Cisco 2811 running CME with a Nortel Option 11C that will soon be IP (Succession) enabled?
Designing a solution for a customer with an existing Nortel Option 11C (soon to be Succession IP enabled) in Moscow...
And we are trying to decide what Voice system equipment he will need in the US (and we have to use Cisco here in the US)
he has multiple requirements (Internet, Wireless voice and data, VPN, Voice, Voicemail, Firewall) and the Cisco UC520 meets them all - just not sure how to trunk this system with the far end Nortel to allow voice over IP + 4 digit dialing between NY and Moscow
SIP, QSIG, Virtual PRI - are all options - but I assume SIP may be best if I can get it working
Another otpion is the 2811 router running CallManager Express if it is easier or more robust for trunking the Nortel with the Cisco internationally
Thanks in advance for any ideas and specifics
