Hi everyone,


Anyone came across a fax tone every 15 secondes on inbound or outbound voice call, a pitch tone (like for FAX waiting to get a farend carrier).

With Call Manager 6.1.2.100 H323 gateway to Cisco 2811 voice gateway using BRI ( Microlink services from Bell)

( he is using port 0/0/0 on the 2811)





This the 2811 IOS version : c2800nm-spservicesk9-mz.124-25b.bin"


The config :

Cisco2811#show run

Woow ... the tone was actually introduced by the 7941 IP Phone that we have there even when we call from that phone to another internal extension we still hear the bip tone...
