Hi, All,

This might be silly but anybody can advise me if I can use PRI to carry voice and data simultaneously? i.e. Allocate some channels for my VoIP traffic and remaining one for my normal IP traffic? Any reference material? Thanks.

Sure it's possible,what router models do you have? The AS5x00 are very good for that, but also the ISR routers can. Depending on the model there are different configurations.

Hope this helps, please rate post if it does!

Thanks for the suggestion. May you illustrate a bit more on this or suggest me some document/readings? Thanks. Currently we are using a Cisco 2851 with VWIC and PVDM.
