IP Trunking (H.323)

[dabramov]

I am trying to connect 3CX Phone System to my Siemens HiPath 4000 V3.0, thru its HG 3550 V2.0, using IP Trunking (protocol H.323). Is it possible ?

Hello,

Unfortunately I do not have a SIP board available (HG 3540), only IP Trunking. Do you have any idea how I can do that ?
