SIP Trunks with Media Proxy Capacity for Mitel Connect HYBRID Sites


To enable Mitel Connect HYBRID Sites, you must allocate SIP trunks with media proxies enabled on one or more switches in Mitel Connect ONSITE. To avoid contention for media proxy resources, for certain switch models (as shown in the table below) Mitel recommends that you dedicate all of the SIP trunks on these switch models to Mitel Connect HYBRID Sites.

You must explicitly enable media proxies for SIP trunks that will be used for Mitel Connect HYBRID Sites:

The maximum SIP trunk with media proxy capacity for each model is shown in the following table. This is the maximum number of SIP trunks each switch supports for Mitel Connect HYBRID Sites. If a voice switch is used for other purposes, then the capacity for Mitel Connect HYBRID Sites would be less than this value.
