Hello TimothyKelley40050



You need to create a SIP trunk from your 8851 Cisco Router to Avaya SM. For configurations you need to refer Cisco SIP trunk configuration document.



Sample from my customer configuration where I have configured with Avaya. If you are well versed with Cisco Configuration then it will be easier for you to work.



dial-peer voice 1000 voip

description ###Outgoing SIP Trunk Towards BRPL Avaya with prefix 0###

destination-pattern 0.......... (11 digits with prefix 0 will be matched and sent to Avaya SM. Change yours accordingly.)

session protocol sipv2

session target ipv4:10.10.10.10

session transport tcp

voice-class sip bind control source-interface GigabitEthernet0/0/0 (Signalling to Avaya via 8851 LAN Interface).

voice-class sip bind media source-interface GigabitEthernet0/0/0 (Media / RTP to Avaya via 8851 LAN Interface).

There are hundreds of posts related to Cisco IP Phones registration with 3rd party PBX, you only need to google or search CSC for that information, examples, files, etc.

If your phone is running enterprise FW, then ignore any post that discusses MPP/3PCC configuration as that would not be applicable to you.

If you wish to migrate to 3PCC/MPP FW to have a configuration GUI for all your settings, you can find the details at upgrade.cisco.com (fees may apply).
