How to find WAN utilisation

Hi All,

We have dialcom (inter site dialing )configuration that uses WAN link for all the calls that starts with certain pattern.

Now we are planning to remove this feature and fall back all this calls to PSTN link (business requirement).

We need to find the WAN utilisation for such calls to understand the impact on the PSTN link.

Please suggest how can we move further.

Thanks,

Saif

How to find WAN utilisation

Is this in conjunction with CUCM? in which case you can do some CDR reporting to see how many calls have gone across the GW that route "the certain pattern". If you cant get the reporting then I guess you will need to do an predictive estimate

using BHCA calculation to do your capacity planning, there is plenty of documentation out in the internets that explain how to calculate this.

Purely looking at your WAN utilisation, might give you some insight if you look at traffic class utilisation (focus on RTP) and packet drops, provided you use QoS. That would be an alternative.
