Hi dear community,
I have a problem when configuring a fxo port in a ISR4331 for receiving inbound calls, I´m new in this kind of configurations.
I have this scenario:
I connect my fxo port to a telephone strip (you know a cable with only 2 pairs), and in theory we received this number 7282851300, next I tried to send this number to my CUCM, I configured an IP phone with only the last four digits (1300) and tried to make a call.
This is the configuration I used:
voice-port 0/1/0
ring number 3
signal groundStart
cptone MX
connection plar 1300
caller-id enable
I used connection plar command because a peer told me the gateway will create this number in order to send it to cucm because is an analog signal.
!
dial-peer voice 100 pots
description Incoming Calls
incoming called-number .
port 0/1/0
!
dial-peer voice 110 voip
description Calls To CUCM
destination-pattern 1300
session protocol sipv2
session target ipv4:10.1.130.247
dtmf-relay rtp-nte
codec g711ulaw
no vad
I activated the "debug voice ccapi inout" command in order to see if something is being sent to my gateway but when I make calls no messages are displayed, I introduced the "sh voice port summary" command and could see that port status change to ringing and connect adn ringing again, I suppose something is happening here.
I created a SIP trunk to connect CUCM and ISR4331.
As I said I´m new in this kind of configurations, so I don´t know if I am forgetting something, so I expect you can help me whit this problem.
Regards.
