[cisco-voip] FXO disconnect problem.

[Todd Simons]

Has anyone solved these problems using an FXS card to a China based
Panasonic KDA-200 PBX?

Hello Hady,
 
With Telecom Egypt, "connection plar opx" solve the problem at most
cases.
But if not u have to check the below, it is working at most cases
 
Get the type of PBX to which the FXO lines are connected . Let the
customer ask etisalat to provide the PBX type to which the FXO lines
connected , and add the following configuration depending on the PBX
type 
 
 
voice class dualtone-detect-params 1
freq-max-deviation 25
freq-min-power 13
freq-max-power 0
freq-power-twist 4
cadence-variation 4
!
voice class custom-cptone UAE-CUSTOM-SIEMENS
dualtone disconnect
frequency 425
cadence 425 325 250 500

voice class custom-cptone UAE-CUSTOM-ERICSSON
dualtone disconnect
frequency 425
cadence 325 325

voice class custom-cptone UAE-CUSTOM-FETEX
dualtone disconnect
frequency 425
cadence 375 375

voice class custom-cptone UAE-CUSTOM-ALCATEL
dualtone disconnect
frequency 425
cadence 375 375


 
 
voice-port 0/2/0
supervisory disconnect dualtone mid-call
supervisory custom-cptone UAE-CUSTOM-XXXXX (use one of the 4 above
cptones, SIEMENS, ERICSSON, FETEX, ALCATEL)
supervisory dualtone-detect-params 1
input gain 14
compand-type a-law
timeouts call-disconnect 5
timeouts wait-release 5
connection plar opx 9000
caller-id enable
! 9000 is the AA extension

 
Notes: 
if the "connection plar opx" or the below configs will not solve the
problem then check the RJ11 cable with the client may be it has the
issue.

Hello ya hady;
 
Two ways to solve this problem:
 
1- Use H323 instead of MGCP on the gateway with the "connection plar opx
" command and in most of the cases it solves the probelm.
2- If you want to use mgcp "or h323 didnot solve it" then you must know
exactly the disconnect frequency that TelecomEgypt send when a call
disconnects "as this is the root cause of the problem that the router
doesnot understand this signal"
 
Unfortunaltly that TE doesnot has a standard for this tone "I asked them
b4 and they told me they didnot care for this" then it depends on the
CO. that you are connected to, anyway the values are so close and they
are as follows:
 
frequency 450
cadence 250 250
 
configure them in a voice class and apply the voice class as a custome
supervisory tone to the voice ports
 
If you need more help I will be more than happy to assisst, I faced this
problem alot here in! Egypt with different CO.s and I think I can help u
ISA.
 
Thanks
