Source notes citing this source

• When an SBC is set to BYOC-P, both the calling and the called numbers on calls from Zoom to the SBC must be in E.164 format. in context
• In the Zoom SBC configuration, the BYOP-P option enables extension-based dialling between Zoom Phone and an on-premises PBX through an SBC. in context
• The Zoom SBC configuration offers an option to allow REFER support for call transfer, applicable to Zoom Phone only. disputed in context
• Creating a BYOC-P/BYOP-P route group in Zoom can take up to 48 hours to complete. in context
• A Zoom route group distributes calls across its SBCs either sequentially, starting with the first SBC in the list, or by load balancing according to the proportion assigned to each SBC. in context
• To change an SBC's IP address in Zoom, the SBC must be deleted and re-added. in context
• The transport between Zoom and a BYOC-P/BYOP-P SBC is TLS only, and the setting cannot be changed. in context
• Zoom SIP Groups attach entities such as phone numbers, external contacts, routing rules and emergency service customisations to route groups, and calls to or from those entities use the SIP Group's route groups; Zoom presents this as a way to phase migration. in context
• A Zoom Phone SBC setting enables T.38 negotiation for fax calls; when it is disabled, fax calls use G.711 passthrough only. in context
• BYOC phone numbers must be assigned to a Common SIP Group to enable both inbound and outbound calling. in context
• The Zoom BYOC configuration guide gives a 10-second INVITE response timeout before failover is triggered. in context
• BYOC SBCs route groups and SIP groups are configured in the Zoom web portal under Product Configuration then Numbers then BYOC Configuration. in context
• Zoom states that route group creation may take up to 48 hours to complete. in context
• A Zoom BYOC route group is created with a route type (BYOC-P or BYOP-P) a region and a distribution method of sequential or load balancing and can name a backup route group. in context
• The support-recreated route group procedure in KB0057948 probably reflects a Hong Kong special case or an earlier workflow since the current configuration guide describes admins creating route groups and backup route groups themselves. inferred in context
• Zoom Phone routing rules for BYOC use regular expressions and can be set at account site or group level with the lower-level rule taking precedence. in context
• When an admin adds a BYOC SBC in the Zoom web portal only the TLS transport protocol is supported and it cannot be changed. in context
• BYOC-P SBCs, route groups, SIP groups and routing rules are managed in the Zoom admin portal under Product configuration > Numbers > BYOC Configuration. in context
• BYOC-P configuration proceeds in order: add the SBC, create route groups containing SBCs, link route groups to SIP groups, assign SIP groups to phone numbers, then add routing rules where custom digit routing is needed. in context
• Creating a BYOC route group may take up to 48 hours to complete. in context
• When a route group is set to BYOC-P, both calling and called numbers must be formatted in E.164. in context
• Zoom routing rules are admin-defined regular expressions that route digits or digit strings to specific destinations and can modify the called number. in context
• The BYOC SBC settings include an 'Allow REFER support to transfer calls' option (Zoom Phone only) that makes Zoom accept SIP REFER messages from that SBC. in context
• The SBC record has an optional Survivability IP Address field that applies only to customers with Zoom Phone Local Survivability enabled. in context
• A per-SBC BYOC setting (Zoom Phone only) enables negotiation of T.38 for fax calls. in context
• When adding a BYOC-P SBC in Zoom, the signalling protocol is TLS only and cannot be modified. in context
• BYOC-P and BYOP-P route groups support only TLS transport, and the transport cannot be changed. in context
