Thanks for the response MIke,
i have the ax set at 15 max digits
but it seems whenever i dial any external no. (9xxx…)the calls get rejected. i had a guy from quintum look at the logs when i dialled and he said i was getting 400 series msgs from the sip. he said i should look at my nrs but that seems fine to me,on the other hand a telecom engineer told me the problem has to be in the quintum. im really confused.
