I think you need to understand how "group" as opposed to "individual" reacts
when both are populated. With both populated, or belonging to multiple
groups with cellerid it can 'revert" to an individual or phone setting.

I've always found that an extra digit also "bothers" the TELCO. When you
send callerid number from a hardphone, what is populated in the user
callerid? Are you transofrming the callerid or are you setting it a gateway
level. If you have too many statements being made, you'll need to know what
to strip away to make it less complicated.

Most TELCO's require you send 10 or 11 digits. So what are you sending in
both a hardphone and softphone instance?
