Notes

In this scenario, the elmeg hybird 300/600™ uses the bintec RT4402™ as the SIP provider. This means that every call that runs from the elmeg hybird 300/600™ via the bintec RT4402™ takes up a SIP channel. So care should be taken that there are enough SIP channel licences available for external connections in the elmeg hybird 300/600™. The same applies to the DSP channels. If you are calling from an S0, UP0 or analogue telephone via the media gateway to the outside, one DSP channel per call is required in the elmeg hybird 300/600™. In the elmeg hybird 300/600™, the call is converted from ISDN/analogue to SIP (one DSP channel required), and the call then goes by SIP to the media gateway, where it is converted back to ISDN/S2M. A DSP channel in the bintec RT4402™ is also used for this final conversion. As this device was equipped ex works with a 32-channel DSP, there is no need to worry here about the number of calls.
