Dynamic Configuration Rules
2.5.4.2.7 IP telephones/clients for ISDN and ITSP Connection in HiPath 3800
Conditions
The following conditions apply to this scenario:
● 100 IP telephones/clients (without H.235) are connected to HiPath 3800 .
● It should be possible to conduct eight simultaneous calls to the ISDN exchange as well as
eight simultaneous calls to the ITSP.
● The voice and data traffic to the Internet is relayed via an external router that also functions
as the firewall. Therefore, the feature “Enhanced B channels“ in the WBM of HG 1500
should be activated.
● 1 STMI2 board is to be used.
Configuration Notes
The IP telephones/clients as well as the calls to the ITSP must be taken into account for sig-
naling. 8 gateway channels to the ISDN trunk are required for the 8 simultaneous calls. No
gateway channels are required for the 8 simultaneous calls to the ITSP thanks to the feature
“IP/IP e2e payload via enterprise proxy”.
