Avaya CM crosstalk with PSTN calls
Hi,
We have Avaya G450 with S8300 and two MM711 modules in a site. There are 07 PSTN lines connected in one MM711 module and the communication manager is configured with basic inbound outbound calling. The client sometime face cross-talk with PSTN calls, for example Phone A is already talking on PSTN line and Phone B tries to get outside line by pressing 9 it will get the same line Phone A already connected on. This problem is random and occurs with around 20% of the outbound calls. Please help me figure out the problem. Thanks, Anees |
Cross Talk

Hi,
Thanks for the reply; following is the CM version details and the analog trunk is "loop start". Please let me know if you need anything further. Current template installed: CM_onlyEmbed 6.2.0.0.3086 (cm 06.2-02.0.823.0, utility_server 6.2.0.0.15) |

Are your mm modules/gateway on the latest firmware for your release ?
Have you had a look at the "show faults" command from the cli of the gateway? Does CM show any errors or alarms relating to this ? If you run a list trace when this happens does it actually show the behaviour you describe ( accessing a line that is already in use) , this would be easily identified using the "status station"(station on active call) and "list trace" (station trying to call out) , multiple sat session can be achieved with a programme such as putty/tutty. I would try this trouble shooting first and post back your findings |
Hi,
thanks for the reply: mm modules/gateway are not on latest firmware. (do you want me to upgrade to latest?) no faults in gateway cli. no errors or alarms on CM. The problem is very rare I tried to capture list trace before but couldn't simulate problem even after several calls, I will try to simulate problem again tomorrow. Thanks. |
I would certainly get the Gateway and MM Cards on the latest firm ware and then run the tests.
