This is Jensen from Yealink technical team, good to know you.
Per this, please help to share more:
1/ Difference handsets registered with difference accounts? or all handset with same account?
2/ How many accounts on this base?
3/ While the issue happened, how about the status of the account?
4/ Please provided the PCAP, config.bin and syslog with level 6.

Jensen it is a difficult issue to pinpoint. The handset randomly cannot make calls unless rebooted or reset. It is version 61.80.0.18 we have tried updating the handset to 61.81.0.30 but this process fails.
To answer your questions.
1/Different handsets registered with different accounts
2/One Account Per Base
3/ When issue occurs we see valid SIP Binding and registration of Base
4/ When issue occurs handset can receive calls. Handset cannot make calls

Rebooting handset sometimes clears error,
If reboot does not resolve, we 'reset handset' through the handset, if that fails
We reboot base.

This process is very inconvenient for the customer
