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
