Scheduled Maintenance
Scheduled Maintenance - Customer Action may be Required Dec 16, 2022 22:00 - Dec 17, 2022 04:00 MST
CT Cloud SIP - ACTION MAY BE REQUIRED

For the past four years, CallTower has had a policy that devices used with CallTower's SIP trunks must support the G.711 codec. The G.711 codec is supported by all known SIP devices, and unless intentionally excluded, your device should already use it. IF YOU HAVE INTENTIONALLY DISABLED G.711 ON YOUR SIP DEVICE, you will need to enable before CallTower's scheduled maintenance window on December 16. After this time, you may experience intermittent audio issues or call failures due to codec mismatch. This is expected and will not be treated as a CallTower service issue - the only remedy is to enable support for G.711 on your SIP device.
