Help with Avaya 5610 and remote IPO 3.0

[BURLYMAN]

I have a customer that has a business office running IP Small Office 3.0. This customer has a home office that has a very solid VPN connected to the office. I am able to remote desktop back and forth, map network drives, etc.. etc.. There are no restrictions on this VPN at all (i.e. firewall rules, etc…) This VPN is router to router configuration so both networks can access each other. I have iPhone on his computer and it works perfectly!!!! It can communicate with the IPO with no problems and make/receive calls. My huge issue is a 5610 phone in his home office. For some reason I cannot for the life of me get this thing to work! I have the 5610 configured with correct settings (IP address is on home LAN, Gateway is on home LAN, CallSRV is the IPO in the business office, and the FileSRV is the VoiceMail Pro server in the business office). The interesting thing is that the 5610 pulls the .SCR and 46xxxsettings.txt files from the remote business office with absolutely no issues (so I know that routing is working perfectly). Then the telephone asks to register with the IPO which works great (after I register an extension the extension is applied within the IPO – and I have tried this numerous times with numerous extensions. When I open the configuration of the IPO the extension shows up just as it should). But then……….the 5610 will hang for a moment and then display “Extension in use # to register”. Even if I manually create the extension, etc. etc.. it acts the same way. The only troubleshooting information that I have is from the monitor which consistently and repeatedly says the same information (the extension in this log is 199):

This looked to me to be a routing problem because after the phone asks to register and the extension is created (from the log above) it says no user responding – so I thought that maybe the IPO did not know how to route back to the extension but as I said all other routing between computers work great. I have checked the IPO IP Routes and even re-created the default route to point to the router at the business office (0.0.0.0 MASK 0.0.0.0 USE 192.168.1.1). I am able to ping the IPO from the home office and I get replies fine. Might I be missing anything???

I have tested the IP phone on the local LAN where the IPO resides and the phone seems to work fine!

Thank you for your help in this matter!

I had just work through this simular problem and I have able to resolve the problem by making sure the 802.1Q was turned off since trunk was not being supported on the SOH side. I not sure if this will help, but it resolve my issue.

I once had the same problem it turned out to be a bad phone.

 

[BURLYMAN]

It was a bad phone? Did the phone work when it was connected to the Local LAN? My phone will work over the local LAN but refuses to work over WAN VPN

 

[milestoned]

I was on the local LAN. I reset it no matter what I did it wouldn't come up. Replaced the phone with a new one it came up.

Your problem is not the phone if it comes up localy. You are looking at some sort of networking issue. What hardware/software are you using layerII/firewall?

Well - I'm fairly confident I have the answer to all of this. Apparently Linksys VPN routers do not support H323 V2 with Fragmented packets. According to Linksys none of their products support it and according to Avaya the routers must support it or it won't work. So - I guess I'm throwing in the towel on Linksys (I do know that the Netopia R910's work like a charm). It's really too bad because unless you have a home office that is willing to shell out a little more for a VPN router that can handle all types of VoIP traffic you are going to run into this kind of thing. Oh well - thats why the IT guys get paid the big bucks right?! Thank you for everyone's input.

Try sonicwall, I have it working and it's a cheap alternitive. Ask the IT guy if he's doing anything speacial to h323 traffic. if so tell him to stop!

I set up the VPN between the sites a while back wihtout knowing that IP Office was going to be used. According to Linksys, once the VPN is up there are no restrictions on traffic and you can't set parameters on the VPN interface so..... Also, according to Avaya Tier4 they have customers that are using Linksys VPN's with no problems they just wouldn't tell me what models (not sure why it would make a difference but I'm sure that it does because Linksys would rather just say "we don't support H323 V2 with fragemented packets" like I heard twice already)
