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.
