3.7 bcm 1.0 srg hardrive failed when making an upgrade for cs1000 to 5.5. only available srg was a 4.0. our tech support gave us an upgrade nortel keycodes for the srg making it a 4.0 bcm 1.0 srg. when trying to register a 1140 phone we get a 'no server ports left'. i can ping the srg and the cs1000 from the phone. what are we missing and what does this message mean? btw, the dn's are set for ip phones.
