Are you using the new internal IP phone VPN features of which you do not have a hardware firewall at your end of the tunnel?
Well as the M0n0wall is not a supported FW for Avaya, and the newer software revs allow a IP phone to direct connect to an IP Office switch "without" specific site to site hardware VPN tunneling protocol, but with internal software inside the phone. I wanted to see how well this FW supports the connection and voice traffic for a stand alone IP phone connecting directly to the firewall at a site with IPO directly without the use of a hardware vpn router as in the past at the other end. We a project of which we want to deploy numerous stand alone IP phones connecting back and was looking for any information on stability of multiple "mobile users" connecting there ip phones in this stand alone configuration before deploying in a customers installation.
Currently we are finding that possibly some audio traffic as in hunt group and the ability to hear all voicemail or auto attendant prompts may not be passing. We are checking to see if it is based on Internet connections or the traffic passing through the FW.
On a side note as well we are testing these phones over commercial satellite with 690ms of delay over the use of a small community phone network and getting great test results.
Another Avaya unsupported area of direction for our company...
Thanks for the input
Just doing our do diligence on collecting data and testing before going to market on a supported solution...
Yeah, the newer software revs allow a IP phone to direct connect to an IP Office switch "without" specific site to site hardware VPN tunneling protocol, but with internal software inside the phone... IP Phone can directly connect to an IP Office switch without the specific site to site HVPNTP....
