The technicians in miy office are trying to install an Avaya ip Telephony solution over a Cisco network, but they are having problems. Just a few calls can get through the cisco routers networks. The network is using IGRP, and i want to know if there is a chance the routing protocol can affect the VoIP??
Hi- First, Avaya VOIP should work with most all routing protocols including IGRP, ( EIGRP, OSPF ).
One issue that sometimes henders VOIP is convergence time.
Are you running STP? Or even RSTP? Although STP has it's advantages, in a VOIP environment the slowness of STP to converge results in calls not getting though. STP in a VOIP setting can also present additional challenges as it can be very hard to trouble shoot.
You do have a coulpe of options if this is in fact the issue.
First, L3 switching with dynamic routes is one.
Another is to contact Avaya. Some vendors have special protocols to replace STPand Avaya is one of those vendors.
