CID manipulation question
|
|
| Steven Jack 2007-11-07, 1:11 pm |
| I wonder if someone can help I am using Callmanager v5.1 which is connected
to our aged GPT/Siemens telephone exchange on a single E1 circuit via a
Westell DPNSS to QSIG gateway and 2821 Router.
To make a call to a pbx extension requires us to prefix the extension number
with 1234, however to call the outside world requires us to prefix 123456.
It seems that I can only add this to a route pattern which means that the
prefix+dialed_number appears on the phone display as the number dialed.
Similarly an incoming call comes in with a prefix 5678 so I have a
translation pattern that takes 5678.XXXX and strips the PreDot, however the
CID now shows the prefix on the dialed phone. I can't add a calling party
mask as I have no way of knowing whether the call is local to the PBX or
external as the all come in via the same route.
It is highly possible I am missing the obvious and would be grateful for any
suggestions

| The same digit manipulation options that are available in Route
Pattern configuration can also be set on Route List level for each
Route Group in that List. Digit manipulation done on Route List level
will not be visible on the phone display and the CDRs. Actually doing
digit manipulation on Route List level is the cisco srnd recommended
way to do it:
http://www.cisco.com/en/US/products....html#wp1043613
("Digit Manipulation in Route Patterns")
Since you have no way to tell which calls are external and which are
internal when coming from the PBX you can also not treat them
differently... the PBX guys could set a different prefix for internal
and external calls when routed to your CCM than you could use the
Translation Patterns to achieve different Calling Party
Transformation...
