Firmware 35.8.0.70
We are currently in Hybrid mode. Mailbox and SFB are hosted in the cloud, phone number is hosted on a Cisco UC PBX on premise attached to SIP trunks.

I have both a yealink T48G and a Polycom VVX associated with a user account.

When attempting to make outgoing calls on the yealink, certain number sequences don't work.
All of the scenarios below work on the skype for business desktop client.

1234 - does not work on yealink; does work on polycom (this is our default 4 digit dial for internal calling)
4-1234 - works on both (this also is allowed via cisco but not the default)
1-212-555-1212 - does not work on yealink; does work on polycom
+1-212-555-1212 - works on yealink; not an option on polycom

Seems to be something with the dial plan settings but the yealink doesn't allow this when in SFB mode, so I can't fix it so it'll append +1 to our calls, nor are there any e164 settings to adjust. Since there's no + key on the keypad, to dial outbound by appending a + requires using the touchscreen keyboard and that's not exactly going to work for people.

I do have a case open with Yealink but they also suggested a post here.
