By default, if SIP trunk is configured all outbound calls will be routed to SIP trunk first, followed by
PSTN. In this lab we will modify the emergency number to route to PSTN only.
o Select Emergency number, 911.
o Under Trunk List Column, select "PSTN only" Click OK.
12. For "Incoming Call Handling", note that the "FXO Trunks Destination" can be changed from
"Custom Configuration" to "Operator." For this lab, choose "Operator" from the pull-down
menu and enter 201 as the destination. The FXO destination can also be set to Autoattendant
pilot once it has been configured. This will be done in lab 3.
.
Click on the Configure button for "Direct Inward Dial Translations". We will use this feature to
add PSTN DID numbers to two of the IP phone users.
o Click on Add for "One-to-One DID Translation"
o Enter a description such as SIPPSTN
o Enter starting DID range as 4085xx1201 and ending as 4085xx1202
o Enter starting Internal Extension range as 201 and ending as 202
This will create a translation for 4085xx1201 to 201 and 4085xx1202 to 202
o Choose SIP Trunk from the Trunks pulldown
o Choose "Use DID" for Caller ID and then click OK
By selecting this option, outbound calls from extension 201 will show called ID of 4085xx1201
and calls from 202 will show 4085xx1202. Calls from all other extensions will show the main
PSTN caller ID, configured in step 10. If you select "Use Main PSTN number" for Caller ID, all
outbound calls on SIP or ISDN trunks will show the main PSTN number as the caller ID
13. Click on the "Users" tab:
o For all the Analog Phones (none connected but configured by default on the UC520):
i. Configure the userid as afxs, bfxs, cfxs, dfxs.
ii. Set the passwords to cisco.
