Connecting IP phones to PBX ipLDK-300 without a SIP?
A: PBX ipLDK-300, VIOP Plata for this ATS, dev Elastix, ISDN PRI \ E1 from the telephone operator with 8 time slots and a bunch of external number, internal telephone network at +|- 100 rooms Task: to Organize a gradual transition to IP telephony. Question: is it Possible to transfer control to a virtual PBX Elastix without attaching a SIP provider using ISDN PRI \ E1 from the telephone operator (the Operator --> Modem --> PBX ipLDK-300)?
Can be done. The issue of funding. If there are no problems would recommend to buy a card Digium TE235BF to make the circuit "operator(E1) > asterisk (E1) > LDK (E1)," then you can gradually migrate to astrik(have done so 3 times with the Panasonic(3 pieces ) and Meredian)
The option is more budget to buy something like Eltex SMG-2

1. Configure the SIP trunk towards Asterisk (Elastix)
2. Set up routing in LDK-300
1. Buy charge E1 and connect the stream to the Asterisk
2. You still need to associate LDK and Aster at least for SIP
