How do you keep dial string contexts and local phone number contexts separate?
Proposal 1: Use separate contexts. Each context handles either dial strings or local numbers. Proxies need to be configured to know which is which:
tel:123;phone-context=acme.com vs. site.acme.com
Proposal 2: New user=dialstring parameter. Userpart is an RFC 3601 dial string with a context userpart parameter. Can have pause and wait:
sip:9,411;context=site.acme.com@provider.net ;user=dialstring
