My customer with using CCME complaint that the post-dial delay is too long for PSTN calls (they have pressed #). Actually we found that the time is more or less the same using CCM. I compared the delay with Notel and Avaya IP Phone system today and found that Cisco is really the slowest with obvious much longer time compared with Avaya. Nortel is the second, Avaya is the fastest. The test is using IP phones of different brands to dial to my mobile. The voice gateway is H323 gateway (except CCME combined with Voice Gateway). Outgoing line using FXO. Can I do something to shorten the delay?
