i hope this isn’t frowned upon !! i have a Sipura 3000 (1 FXO, 1 FXS) that i no longer need. it was purchased to demo an Asterisk system and hasn’t been used since. most of it’s time in use has been configuring it to work properly with UK POTS and Asterisk.
open to offers, you can have it configured as is for use with Asterisk, or reset to factory defaults. i’ll even throw in the RJ11 -> BT adapters.
the only proof i can offer of my trustworthiness is my eBay history … same id as this one !
