VOIP over Frame Relay

Can some refer me to a link or can have the config. I have central site with 3 remote sites. All are T1 from the ISP. I need to configure the QOS to provide Voice over IP over frame.

Thanks

Re: VOIP over Frame Relay

Hi,

Assuming you know how to configure VoIP then configure that as normal.

You must either setup a new PVC for the voice, or you must traffic shape to prevent any bursting above the CIR on the converged PVC.

As your link speed is less than 2M i'd consider using FRF.12 fragmentisation to ensure you don't suffer from adverse jitter problems. Be wary of tandem-switching if a remote site wants to dial another through the main-site.

Enjoy!
