Alcatel —> 2901 (3xxx) <-----------------Fibre IP LINK---------------> 2901 (in Data Centre) ------->Primary IP PBX
I have ironed them all out apart from 1 and I am completly stumped - I would really appreciate some help.
Alcatel handset rings an IP handset - Call established. Alcatel handset wants to transfer call to another Alcatel handset so they enter number. At this point the Asterisk MOH kicks in and plays to the IP handset. Alcatel handset puts call through and hangs up but MOH does not stop on IP handset however there is one way audio. The Alcatel handset can hear the IP handset but the IP handset is still listning to MOH.
I don’t understand how the Alcatel is able to initiate the Asterisk MOH rather than it’s own.
My question is basically - Is there a way to stop the Alcatel from initiating MOH on Asterisk?
I have investigated and still no joy. I forgot to mention that there are 2 2901 Cisco routers between the PBX and Asterisk which I am convinced are the cause of the issue but I can’t for the life of me suss it out (i’m not getting any help on the Cisco forums either)
