Having 2 kinds of analog lines from different provider:
1. "WORKING" national/international
--> the following VG config works well, signaling frequency have been measured to set-up accordingly. NO PROBLEM!
voice class custom-cptone EG-Giv
dualtone busy
frequency 1415 1820
cadence 200 300 200 300
dualtone disconnect
frequency 450
cadence 250 250
voice-port 0/1/2
trunk-group AnalogTrunk2-EgyptTelecom-OutInt
supervisory disconnect dualtone mid-call
supervisory answer dualtone
no battery-reversal
cptone EG
connection plar 2761400
impedance complex2
description <REMOVED>
station-id number <REMOVED>
caller-id enable
2. "NOT WORKING" mobile
--> Cannot find a proper configuration, symptom for outgoing AND incoming calls: DIALING STATE --> RINGING STATE --> CONNECT STATE (and call is disconnected)
After line measurements, state voltage are the following:
Call Cycle in DC voltages
On-hook state 48V
Ringing state -38V 38 V in 1st ring, then 0V then 38V starting from the second ring onwards
Answered state -11V
Disconnect state 11V
voice-port 0/2/2
trunk-group AnalogTrunk3-EgyptTelecom-OutMob
battery-reversal
cptone EG
connection plar 2761400
impedance complex2
description <REMOVED>
station-id number <REMOVED>
caller-id enable
--> Tested with & without "battery-reversal", but did not help. According to voltage change, "reverse polarity" as stated by telco provider should be translated to battery-reversal ???
--> Found Cisco doc but did not help: http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00800ae2d1.shtml
Anyone face similar problem ? (IOS version: 124-20.T)
Any idea to get it working ???
PS: the line is known to be working as it was primarily connected to TDM PBX
Solved! Go to Solution.

The cause of the problem is that incoming calls across the FXO was sent to another FXO port instead of being sent to CCM. This causes both ports to get stuck in connect state.

Hi Guys,
I finally solved this issue, by adjusting fxo lines as follow:
voice class dualtone-detect-params 1
freq-max-deviation 25
cadence-variation 4
voice class custom-cptone EG-Giv-Mob
dualtone busy
frequency 425
cadence 200 200
dualtone disconnect
frequency 425
cadence 200 200
voice-port 0/2/1
trunk-group AnalogTrunk3-EgyptTelecom-OutMob
supervisory disconnect dualtone mid-call
supervisory answer dualtone
supervisory custom-cptone EG-Giv-Mob
supervisory dualtone-detect-params 1
no battery-reversal
timeouts call-disconnect 5
timeouts ringing 10
timeouts wait-release 5
connection plar 2761300
description
station-id number
caller-id enable
Hope that can help others ;-)

Hi DCohen, which debug command(s) do you use to be determine which parameters to adjust?
Thanks.
