However, we've found that this is a problem as it provokes duplicated linkedid entries on our CDRs, which is caused by the fact that the internal linkedid field used by asterisk is 32 chars, while uniqueid is 150. (See: http://www.asterisk.org/doxygen/trunk/cdr_8h-source.html#l00124)

Having a 32 chars limit on something that should be a DNS hostname is just wrong. Change it.

Chan_sip use the systemname as a realm and a realm should by default be a unique string, like the DNS host name which is globally unique.
