IP Office capacity

[29091305]

I need a unit with a capacity of more than 380 extensions.
I think the IPOffice does not reach this capacity. That model could install?


thanks Guys.

what type of extensions?

Extension Capacity

The maximum number of H323 IP phones supported by an IP Office system is based on that system's maximum capacity for extensions of any type as listed in the table below. To find the capacity for IP phones remove the number of physical non-IP extensions installed on the system, ie. extension ports on the IP Office control unit and any external expansion modules.

1. The maximum extension capacity is 28 for all phone types but only 16 may be IP phones.
2. Fixed non-adjustable capacity.
3. 384 for IP Office 5.0+. 272 for earlier versions.

We have one with a second IPO just for analog devices such as fax/modems. We also use that ipo for extension like conference rooms, those rooms don't use much features like PhoneManager.

I have a system with 400+ extensions - combo of analog digital and IP stations. Running for two years without an issue. However, should you have an issue, you may have trouble getting official support.

Hello HSM,

Did I put all the values in the right columns? (This TGML stuff drives me nuts...

In another thread there was concern expressed over a lot of SIP traffic combined with IP phones. Is there any rule of thumb one should use in balancing SIP trunking and IP phones before going to TDM trunking from a SIP gateway so one doesn't overload the IPO's processor?

Thanks,
WN

If you are already close to or exceeding th emaximum design capacity I would suggest that IPO is probably not the correct solution for your needs

IPG,
That is definitely a possibility that must be considered.

I am hoping to draw on everyone's experiences with what they have observed as the maximum-capacity threshold is approached. The lab tested capacities may be very different from capacities experienced in real-life field deployments. In our case we are relying on the majority (90%) of our traffic arriving on SIP trunks and being sent to IP phones. In a recent discussion in the forum it was brought up that SIP traffic is rather processor intensive and it might be best to use a SIP gateway to send traffic through E1/T1 cards to the IPO. That is an expensive way to handle calls, but somewhere there may be a point where that might be necessary. I am hoping the group will be able to share some of their observations that would help to determine the cross-over point, whether that would be multiple IPO 500 units using SIP and IP phones, or fewer IPO units with E1/T1 cards and SIP gateways. We cannot get away from the SIP trunks and IP phones because of the need for diverse locations and necessary flexibility of deployment and configuration.

Thanks,
WN
