K12 school is upgrading the PBX and we are implementing UC500 series for 30 endpoints. School also has 30 2 way legacy intercom system that they want to integrate with the PBX. Since UC500 doesnt support SIP, anybody know of a 3rd party that would do this? I cant do it with FXS ports since there are so many 2 way intercoms and it would be nice to do it SIP based.
I could go with BE6000 or CME but the price difference would scare away this customer.
