AS5400 HPX is it possible to perform call in G729 (means high complexity )

Hello

We use à AS5400HPX HW with the following card

slot 1 NP 60 DFC

slot 7 E1 8 PRI DFC

the ios is 12.3 based

The configuration of the gateway is for working in H323 protocol with

specific dial-peers for the calls depending on the services.

Form point of vue of the coedc a liste of codec preference has been set

the first one is

g729r8

then the g723r63

according the msgs, in the TCS, we can see that the list is g729a, and g729

There is no command to specify a codec G729 / G729a on the GW

my question is the following.

According différent documentation I have seen on the cisco site, I have understood thatr

the AS5400 / AS5400 HPX is not OK to perform high complexity codec (mean work as G729)

It seems that it is the case when we enter the command

>>>>>>>>>>>

there are only calls in G729A and G711

do you know the documentation

http://www.cisco.com/en/US/tech/tk1077/technologies_tech_note09186a00800b6710.shtml

it seems that it is impossible to perform G729 high complexity with AS5400

is some able to confirm this fact.

I have also seen on cisco site that for AS5400XM and AS5350XM(?), it possible to plug Voice feature cards

known as "CIsco High-Density Packet Vice/Fax DSP Module" (AS54-PVDM2-64) and with this card it is poissble to

provide high density voice connectivity. >>>>> Means the Codex complexity could be configured as high complexity

method.

One some other cisco Equipment (ex routeur 3725 it is possible to add NM-HDV Hardware board)

known as Feature voice-card. With this equipment, it is possible to configure high complexity

codec as mentionned in the previous link with conf t + voice-card

so what happens if a such configured router is connected to AS5400HPX with the mentionned configuration ?.

Is the DFC card is able to adapt the communication in high complexity

Thanks for the informations

From the past experience, it appears that G729 variants r8 and r63 are not supported and it has interworking issues with other gateway if these variants are intended.

Routing function may be performed together in the same box alongwith vfc card.
