IN CASE THE CALLER ID OF INCOMING CALLS IS
NOT RECEIVED CORRECTLY
1. Log in to the console in Elastix Server. You can access remotely or directly from
the server.
2. Go to /etc/asterisk/extensions_additional.conf and search the context of the inbound
route configured in Elastix. As a reference try to find the DID number we set. In
this case the name of the context is [ext-did-0002]. See Figure 4-15.
Figure 4-15
3. Copy the context and paste it at the end of the file
/etc/asterisk/extensions_custom.conf and change the context’s name to [route-gs-
elx]. In addition to this, add the following lines to the context starting from the third
line:
exten => 999999,n,NoOp(Obtaining CallerID ...)
exten => 999999,n,Set(foo=${SIP_HEADER(P-asserted-identity)})
exten => 999999,n,Set(cadnum=${CUT(foo,:,2)})
exten => 999999,n,Set(CALLERID(number)=${CUT(cadnum,@,1)})
exten => 999999,n,Set(CALLERID(name)=${CUT(foo,\",2)})
The context should end as shown in Figure 4-16.
Figure 4-16
4. Add the line context=route-gs-elx in the Peer Settings of the SIP Trunk
configuration in Elastix Server. Refer to Figure 4.6 on step 9. At the end the SIP
trunk configuration must be as shown in Figure 4-17.
