[Asterisk-Users] connect Asterisk with Siemens HiPath HG1500

[Joao Pereira]

Hi
I want to know the best way to connect Asterisk to a Siemens HiPath HG1500
PBX. Until now I came out with 3 solutions:

1-Asterisk being a H.323 client of the Siemens PBX (I believe it needs
Siemens licences and Digium hardware)
2-Asterisk connecting to the PSTN phones with Voice Modems (good ideia!!!
but its analog... doesnt have caller information...)
3-Using RDIS interfaces to connect the Siemens PBX

does someone have other ideias?

Thanks
