| Fax/T.38 transcoding | | | | This feature involves taking a G.711 call with FAX tones and transcoding to T.38, and T.38 to G.711 FAX in reverse direction. See Fax Over IP. |
- T.38 (V3/V0) pass-through fax calls
- G.711–T.38 (V3) fax transcoded calls
- T.38 (V3)–T.38 (V3) fax transcoded calls
Fax/Modem fallback | | | | This feature involves allowing a compressed call to switch to G.711 mid call for FAX transmission.See Fax Over IP. |

Maximum number of call legs | 1/2 of UDP media port range | Based on number of IP addresses per interface and UDP media port range | See SBC SWe Performance Metrics | Two examples assuming 64,000 media port range: - SBC 5000 series number of call legs = 32,000
- SBC 7000 series number of IP addresses = 6 / number of call legs = 110,000

| Maximum number varies based on - server hardware where VM is deployed
and - VM vCPUs/memory configuration.
| For example, SBC 7000 4K/40K profile is comprised of: - 4,000 instances each of Address Contexts, Zones, IP Interface Groups, IP Interfaces, Signaling Ports;
- 40,000 Trunk Groups
