To be up front we don't use Cisco VOIP it's MITEL.
I have two sites that cannot talk to each other. At first I thought it was a call routing issue so I checked all the routes and made sure each PBX has the correct numbers and IP addresses all is fine nothing has changed. Then when I tried pinging each others IP address from within the Mitel I couldn't reach each other. I started down the network path but from each router I can ping the others PBX IP address so I know the route is there.
The PBX know's its default gateway and can get there just fine and can ping all the other PBX's IP's just fine. Am I missing something obvious.
Thanks for the reply. It's a Point to Point T1. There is no ACL and I have never looked into doing a trace route from the PBX it turns out I can. Now I haven't used this alot but when I did the trace to the IP address of the other PBX it gives me the first 4 hops then request time out all the way till 30. I will look at at the last hop and see what I can figure out.
Little confused now. I assumed when I went to the last hop on I wouldn't be able to ping the IP address of the PBX I'm trying to communicate with. I was able to ping it....not sure what I'm missing or what steps I would take next.
Yes, neither PBX can ping each other. I think I have it figured out or narrowed down.
PBX A Router A
PBX B Router B
Router A can ping PBX B and Router B both data and voice vlan, Router B cannot ping PBX A voice vlan but can ping the data vlan's IP. When I look through the routing table of Router B there is no route to Router A's voice vlan and Routers A gateway of last resort cannot get there either. We just changed from OSPF to EIGRP. I don't have extensive experience tshooting OSPF and very little with EIGRP. I'm studying for the CCENT currently.
could you answer this. When I do a trace route from PBX A to router B's mgt IP it stops after 3 hops. Like I said in the post above when I go to that last hop I can ping that IP and PBX B from that router so if the trace route stops at that hop what is that telling me in this scenario?
