We have 1 T1 comming into our offices. We have it setup for 128k for data and the rest for Voice. can anyone tell me what changes I need to make to the following config to bump the data up to 384K. We are stealing the bandwidth from the voice. What should I be concerned about on the voice side? Thanks for the help guys

Yes this has been done they are suppose to do what they call a turn up today at a certain time. My problem is the people who do the router changes for me most of the time are unavailable and this is kind of an emegerncy situation. We use a Phone system that divides the channels up. I am just trying to get a idea of what changes I will have to make when the time comes so I do not look like a complete dummy.

You need to contact your T-1 provider, you can't just split them on your own. T-1's are broken up into channels and you need to grab more channels for your data and less for your voice. The end result with voice is less channels so it really depends on how your system is setup. Are you using analog channels and you have say a dozen phone lines or do you have a phone system that divides the voice channels up to allow for the typical oversubscribing of voice channels to end users.
More info on the phone system is needed. Let me know if this helps.
