We have a 81C with a Cisco call manager, we are trying to call a remote site in Colorado that is hooked to a Octel. When dialing from a Nortel phone it gets stuck on the far side into a menu service, when dialing from one on the cisco phones it will ring to the persons extension on the far end. I have traced both calls, they go out the same route and loop number for long distance. Why would the cisco call connect and the nortel call not connect? Any help would be great! Thanks!!
