For years in different applications we have been using Multtech analog to SIP adapters:
http://www.multitech.com/en_US/PRODUCTS/Families/MultiVOIPFX/ However, it appears Multitech as a company is getting out of the VoIP business. I love that they have 1/2/4/8 port versions and they have always "just worked" for us.
What do you guys use for this type of thing. My current scenario is a 2 building phone install. building 1 will house a single 3300 ICP, and the 2nd building (connected via a wireless bridge) will house 8 IP phones, a CC, Fax and analog conference phone. My design had a 4 port Multitech in the 2nd building. One of the 4 ports of the multitech was going to go to an analog trunk from telco to be used for 911 calls from that building, and the other 3 to run the various analog devices.
The main building will have a PRI.
Needless to say I'm bummed out about losing Multitech.....what do you guys use for this type of thing?
