Hi, I'll try to keep it short. A customer wanted a 2 digit pbx, but after a few years the company growed and the 2 digit numbers flew out the door. In V10 I took advantage of a bug ... if you had configured a 2 digit configuration on the pbx, you could use 3 digits in the ring groups (and it worked). So I was able to create more digits then a normal 2 digit pbx (which was very usefull !) Now our customer could upgrade for free to v11 and so he did. But recently I had to make some changes to a ring group and I am unable to edit the existing ring groups with 3 digits. it keeps telling me "The extension number length is 2" So then I liberated a 2 digit extension to be able to create the new ring group, but then I get the message that "a new extension could not be created because there are no more availble extensions" If I make a regular extension (normal phone) I am able to create this new user. But not a ring group / queue or digital receptionist with the free 2 digit extension. Is there some kind of workaround for this ? Other then reconfiguring the whole PBX with 3 digits ?
