the UC500 has an option to define maximum calls out the WAN interface (FastEthernet
0/0) using the below example which limits to 3 total calls:
call threshold interface FastEthernet 0/0 int-calls low 3 high 3
For QoS (Quality of Service) by default the UC500 is setup to mark SIP packets
(signaling) as cs4 and RTP (media or audio) packets as cs5. This can be changed via the
below CLI on all VOIP dial peers used for the SIP Trunk:
dial-peer voice 1000 voip
ip qos dscp ef media
ip qos dscp af31 signaling
4.4.7 Call forward caller ID (calling-number local)
When calls get forwarded from the UC500 to the SP, the caller ID field is by default set
to the original calling number. For example if PSTN A (4084441234) calls IP phone A
(4085551001) & phone A is set up for CFA (Call Fwd All) to another cell phone on the
PSTN (4083331234) – the INVITE for the second call will have the caller ID of PSTN A
4084441234. Some SP soft switches will not process the INVITE as the From header
in the INVITE is not a DID on the UC500 – to overcome this you can setup the caller ID
for call forward or transfer to be the UC500 phone that initiates the feature as below:
telephony-service
calling-number local
4.4.8 Creating a specific Dial Plan for outbound calls
The default dialplan when using a generic SIP Trunk provider template sends all calls out
a single dial-peer which implies that Class of Restrictions (COR) do not apply. This can
be changed using "dial-peers" as desired. An example using the North American
Numbering plan (NANP) is shown below:
dial-peer voice 11001 voip
corlist outgoing call-local

destination-pattern 9[2-9]......
