VoIP, FXO, FXS, DSL and MTU (Can we all just get along?)
Posted on 2006-05-23
Hello experts! Here is my question, but first my topology.
I have 7 remote facilities that are calling centers. Their data networks connect via IPSec over DSL (6.0mb down | 512Kb up) back to corp utilizing a MTU of 1410 and yes it is mandatory to use such.
My question is what product or how would you recommend me doing the following?
I would like to have users at corporate be able to pick up a phone and either through the pbx OR through a device attached directly to the phone be able to connect to one FXS or similar device that would answer and send a off hook to the device that it is plugged into.
Here are the particulars:
The FXS device/remote device must be able to adjust it's MTU from 1500 to 1410 in order for all packets to not be fragmented and make it to it's destination.
Each branch office will have a maximum of two conversations. (Optional:one conversation at any time would be acceptable)
We would like to not have to buy equipment on a 1 to 1 ratio, meaning for every remote device we must have a corresponding device at corporate that works only with that associated fxs or similar device. If it was possible we would prefer buying something that provided a multiport capacity for our analog equipment.
Ok I think that does it questions/suggestions?
