Acme 3820 - Lync CX600 / CX3000 beeping on outbound PSTN calls
We recently purchased 5 Acme Net-Net 3820 SBCs & we are having this 3 to 5 beeps on our Polycom CX600 / CX3000 phones.
This does not happen on our other SBCs (different vendor) or our Cisco voice gateways.
The Acme SBCs are on the same subnet as our other SBCs (same fw/acl rules) and pointing to the same Lync servers.
Any help or advice is appreciated.
