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
