Description

Cisco IOS® Software Release 12.0(2)XH is a short-lived ED release that introduces support for the next generation voice domain specific part (DSP) (DSPM-549) on existing voice carrier cards in the Cisco AS5300 platform. This release also introduces functionality that doubles the number of T1, E1, and Primary Rate Interface (PRI) ports from the previous limit of two to four. In other words, the AS5300 will now support up to 96 voice calls in T1/PRI configurations or up to 120 voice calls in E1/PRI configurations when configured with AS53-VOXD (T1 549-based) voice cards and using Cisco IOS Software Release 12.0(2)XH or later. Additionally, this release delivers initial support for the G.723.1 and G.729a voice coders (out of band dual tone multifrequency (DTMF) transport for coders that don't transport DTMF well) and codec negotiation.
