Indexing phone numbers & sip addresses in lucene is complicated. Most people use ngram tokenizers. We did that for a while with ngram min=3 & max=35, but the result was often 100s of tokens per sip address. Working in a call center focused company we quickly figured out how wasteful that is on the storage front. For us 6/7ths of our indexes were waisted on useless sip address tokens.
It's a hard problem to regex your way out of. An international phone number often includes a country code, but that can be 1, 2, or 3+ digits. A lot of people have requested elasticsearch integrate google's libphone library into a custom lucene analyzer. It hasn't happened yet, so here's a plugin that attempts to do just that.
Note: This is a young project we're just starting to do testing on 8/3/2015. We'll improve as time goes on, but use at your own risk.
mvn package
./bin/elasticsearch-plugin install file:///....elasticsearch-phone/target/releases/elasticsearch-phone-1.2.0.zip;
Provide a telephone or sip address prefixed by "tel:" or "sip:" with no spaces or symbols.
Your indexing template will need to specify the analyzer for the field. EG "dnis": { "type": "string", "analyzer": "phone" },
