Re: [SR-Users] Problem with callid as htable key

Just to add that regexp matching when using keys from the sip message such as call-id is exposed further to some issues -- for example, it is common to have . (dot) in call-id, which for a regexp is matching any char, so a call id having 123.456 is matching 123x456. So depending on what you want to count, might be better to match by equal or prefix rules.
