Compatibility CP860 with other SIP Server

[albani]

Hi,
I am new for Yealink products. Currently, we have project which is my client want to use Yealink Conference devices such as CP860 to combine or join with existing SIP Server using CXS Netspire Communication Exchange (Product Code :SVLCX03).
This Netspire has Protocols :
RFC3261 SIP; RFC3550 RTP, RFC3170 Multicast; RFC2131 DHCP; IEEE1588 PTP v2; RFC1157 SNMP; RFC958 NTP
Encoding :
48kHz 24-bit PCM (1152 kbit/s; 24kHz audio bandwidth)
48kHz 16-bit PCM (768 kbit/s; 24kHz audio bandwidth)
CELT (64 kbits/s; 22kHz audio bandwidth)
G711 µlaw / alaw (64 kbit/s; 4kHz audio bandwidth)

We still in technical review phase so we don't have any Yealink product sample to test the endpoint CP860 with these SIP server.

Could you or someone please to assist me to state and proof it that Yealink CP860 and its varian is compatible with Netspire Communication Exchange ?

We much appreciate and hearing your advise.

Regards,
Albani
