Compare domain sections of SIP URIs.
For hostnames, a case insensitive string comparison is used. For IP addresses, a binary comparison is used. This is mainly because IPv6 addresses have many ways of writing the same address.
For specifics about IP address comparison, see the following document: http://tools.ietf.org/html/draft-ietf-sip-ipv6-abnf-fix-05
- Parameters:
-
host1 The domain from the first URI host2 THe domain from the second URI
- Return values:
-
0 The domains match nonzero The domains do not match

helper routine for sip_uri_cmp to compare URI headers
This takes the headers from two SIP URIs and determines if the URIs match. The rules for headers is simple. If a header appears in one URI, then it must also appear in the other URI. The order in which the headers appear does not matter.
- Parameters:
-
input1 Headers from URI 1 input2 Headers from URI 2

helper routine for sip_uri_cmp to compare URI parameters
This takes the parameters from two SIP URIs and determines if the URIs match. The rules for parameters *suck*. Here's a breakdown 1. If a parameter appears in both URIs, then they must have the same value in order for the URIs to match 2. If one URI has a user, maddr, ttl, or method parameter, then the other URI must also have that parameter and must have the same value in order for the URIs to match 3. All other headers appearing in only one URI are not considered when determining if URIs match
- Parameters:
-
input1 Parameters from URI 1 input2 Parameters from URI 2
- Return values:
-
0 URIs' parameters match nonzero URIs' parameters do not match
