Intermittently unable to make external calls

[shane.moorcroft]

Users have been complaining that intermittently when they try and make external calls they will dial a number and CALL PROCEED will appear on the screen of the phone ( 7960 ) and they then get no dial tone and nothing more happens.They then put the hand set down and can try agian and the phone call goes through. This has been reported on a total of nine phones but at different sites.Could anyone tell me what the call proceed means and if they have any ideas as to what could be causing this. Regards

assuming h323 gw, try these 2 docs and see if they help

I am experiencing the same problem and it appears to us that it occurs when the dialed destination is busy. What version Callmanager do you run and what firmware is on the phones, we are running version 3.3.3(sr4a-es46) which is an engineering special and firmware version P00307010100 on the phones.

We recently upgraded to this CM version and prior to the upgrade we did not have this issue. I have run a trace and captured the problem so will have a better look tommorow, and keep you informed with what we find. Regards,

Hi Shane,

is the callmanager direct connected to the gateway via mgcp or h.323?

Do you have some more informations about your environment (ie. cm, gw).

Hi Micheal

We have been able to resolve our issue. After investigating it was established that the call proceed was only occuring when internal users dialled an external number that was engaged. Same symptons as simon wilson is experiencing. We also have recently done some upgrades on CM and the firmware on our phones and the call proceed message only started appearing after the upgrades. After reading the articles posted by aamercado we have found that two global commands issued on our h323 gateways resolves the problem and our users get the engaged tone instead of the call proceed message. We have implemented this on 6 of our remote sites and main site and it has resolved the problem. The two specific commands were : VOICE CALL SEND-ALERT and VOICE CALL CONVERT-DISCPI-TO-PROG

Simon , the problem you are experiencing sounds exactly the same as ours. If you have not already resolved your issue maybe the above will help.

Many Thanks for all your responces

Shane, the command 'voice call convert-discpi-to-prog' solved our issue too. Many thanks to all.

Rgds,
