1. Ensure that ShoreTel requirements are met
    • Each SIP extension needs 1 IP Phone and 1 SIP proxy
    • One analog port = 5 IP Phones or 5 SIP extensions = 100 SIP extensions or 100 SIP proxies
    • To add a license, follow this path: ShoreTel Director > Administration > System Parameters > Licenses > Keys > New > type in a valid key
    • Ensure codecs are available for SNOM SIP:
      • Administration > Sites > click on a site where this SIP phone is located > check under Bandwidth verify these settings
        • Admission Control Bandwidth = 1024 kbps
        • Intra-Site Calls = High Bandwidth Codecs
        • Inter-Site Calls = Low Bandwidth Codecs (this option doesn’t exist in older ShoreTel systems)
        • Fax and Modem Call = Fax Codecs – High Bandwidth
      • ShoreTel Director > Administration > Call Control > Codec Lists > click on the codecs list that has been selected in the previous step > ensure that PCMA/8000, PCMU/8000, and G722/8000 are available on the Codec List Members
Typical Settings:
High Bandwidth Codecs
G722/8000
BV32/16000
L16/8000
PCMU/8000
DVI4/8000
BV16/8000
G729/8000
 
Good Rule of thumb:
— Internal —
PCMU (G711 ulaw) – toll quality
PCMA (G711 alaw)
G722 – most widely supported & backward compatible with G711, good quality
— Internet SIP Trunk —
G729
— NeoTel Standard —
G723
