15.4 Examples of number mappings
SwyxWare offers great flexibility for incorporating inter-location scenarios into number mapping. The following examples will show just how very flexible it is.
SwyxWare With Three Locations
There are three company locations: London (+4420), Manchester (+44161) and Germany (+49). A SwyxServer with ISDN access is installed in London; at the other locations, there is a separate gateway with ISDN connection to the public network. Furthermore, the headquarters in London is connected to a SIP provider. This means that there are four trunk groups (3*ISDN + 1*SIP) each with one trunk.
User A
has the internal number 323. Two numbers are assigned to this user. One is a London number (+44 20 1234-323) and the other is a Manchester number (+44 161 6623-14). This user can therefore always be contacted via his Manchester number, even when he is in London.
If the subscriber is in Dortmund but calls a number in Munich, his call can be routed via the gateway (trunk) in Munich and thus his call number in Munich (49 89 6623-14) is signaled to the caller.
Other internal callers dialing from anywhere in the company can contact him at any time via his internal number (323).
User B
has the internal number 222. The London number ’+44 20 1234-222’ will be assigned to him. He also receives the URI "jones@company.com".
Other internal callers dialing from anywhere in the company can contact him at any time via his internal number (222).
User C
has the internal number 410. Both a London number '+44 20 4777-410' and a German number '+49 34501-12' have been assigned to this user. This means that he can be contacted via a London number and a German number.
Other internal callers dialing from anywhere in the company can contact him at any time via his internal number (410).
If the user calls a number in Germany from London, his call can be forwarded via the gateway (trunk) in Germany and, therefore, his number in Germany (+49 34501-12) indicated to the caller.
