Hi there, i need help!!!
I have one-way voice problem between two cisco 3600 series equiped with NM2V and VIC-2BRI-S/T-TE, in both sides of voip connectivity and 2 alcatel pabx's; the first pabx is omniPCX 4400 and dhe other is 4200 E. On the 4200 Alcatel side, i'm getting this output from "debug isdn q931":
ETSI supplementary service not supported;
Mandatory Information Element missing;
the call is successfully from omnipcx 4400 side to 4200 E side but is only one-way voice. In the opposite side, i'm getting only a short ring and nothing else.
I really need help
chears guys!
