Ok here is my problem. I have a BCM400 in Houston and a BCM 200 in Florida. I have a Contivity 1010 at each loaction with a Branch Office tunnel nailed up between the two sites to make them all one domain. Utilizing the 400 in Houston as a call center we register all IP phones as S1 to Houston. We have several remote agents that Contivity Client into the Florida office and then register to the private LAN 1 on the Houston BCM.

This always works perfect.

Now that Florida has had the storm the Florida location is without power. We are having the remote agents now client into the Houston Contivity 1010 and register to the private LAN 1 on the Houston BCM. They register and get a DN just fie but there is NO VOICE and sometimes 1 way voice. Since we are taking a huge portion of the puzzle out of the picture you would think that it would work just fine as Houston has a PRI and a T1 for internet and alswo it works when you go through Florida. I built a user in the base group on the Contivity and it still did not work. I cannot check the Florida Contivity to see what may be different as they are down. ITAS has not been any help and I have a customer that is loosing money everyday. YOU GURU's ANY IDEAS????

Are you sure they have routing both ways between the LAN's. Are you using NAT. NAT has always been a problem generating one way or no way speechpath... So if you are tunneling you have do disable NAT support on the routers interface... This is not a solution, more like a suggestion to what might be wrong...

Let me add this. I also have a contivity 100 at each location. This is used for a branch office tunnel to a software host that the company uses. In the Contivity 1010's we have a one armed route that points the "software host" traffic out the 100 and everything else out the 1010. I do have to have the NAT rules in place for this to happen. I have 4 rules in place. This is the same in Florida and in Houston. Why would it work into the 1010 in Florida and accross the tunnel to the BCM in Houston but not to the 1010 in Houston then to the BCM in Houston?

Here is what is happening this morning. I have a Client into the Houston 1010. i2050 regestered to the Houston BCM LAN 1 private ip. It has worked fine for about 35 minutes. Just stepped away from my laptop for about 5 minutes and now the softphone is still up but I cannot hear anything on it. It will place and receive calls, I can talk from the i2050 and the other party can hear me but I cannot hear anything on the i2050.

The only reason I asked about the calls between Phones is each call that was transfered or made betweeen the IP phones would have stopped at Florida rather than going to Houston each time. Now they will relay through Houston all the time and I was wondering was it a latency problem or somewhere in the network that has not got a vpn route.

When I make LAN 2 published with a public ip address, I can establish a softphone to Houston from offnetwork and it does the same thing as through a client. The i2050 cannot hear anything.

Have you confirmed the correct firewall ports are open for the IP telephones. The reason I ask is you are connecting to Florida with IP phones and then sending your calls to Houston as IP trunks.

Here is what I did this weekend. I completly factory restored the 1010 in Houston, did a diskless upgrade and reprogrammed. It is working like a champ. 100% success rate since this has been done. Corrupt code on the Contivity. Thanks for all the help~

Are we talking about telephone systems or a customer's data network? I though that this was a forum for TELEPHONE systems?

There are only 2 seasons in Canada, Golf and Snowmobile season.

As you kow that line is getting harder and harder to say.

How about a telephone system that resides on a customers data network.....

And seeing how stable and reliable most data networks are, you are willing to put your communication "life line" on a network?

I don't know about you, but if I owned a business with an office and needed a phone system, I would not trust my phones on a network. I want my phones to work in a stable and reliable manner that cannot be obtained by tying them in with a data network.

Skippy440, why did you buy a BCM? There are cheaper digital systems out there.
