problem with the voice volume between incoming and outgoing calls

[orangel]

Hi all.

I have a situation with volume calls.

1.- When the calls are originated in the PSTN to the IP Phones, the volume is ok in both sites.

2.- When the calls is originated in the IP Phones to the PSTN, the person in the PSTN listens very low.

I try to adjust the volume in the voice-port configuration, increasing the input and output db value, but not if I am doing it well or if I need adjust the configuration in other part.

The router 2801 have a CCME ver 4, this router is connected to PBX with a E1 and the PBX have the PSTN Digital trunks.

this is the voice router configuration:

voice-card 0

dsp services dspfarm

!

voice service voip

allow-connections h323 to h323

supplementary-service h450.12

!

controller E1 0/0/0

framing NO-CRC4

line-termination 75-ohm

ds0-group 0 timeslots 1-12 type e&m-immediate-start dtmf dnis

description to the PBX

!

voice-port 0/0/0:0

auto-cut-through

input gain 4

output attenuation 4

playout-delay nominal 200

playout-delay minimum low

bearer-cap Speech

try these settings:

voice-port 0/0/0:0

input gain 1

output attenuation 2

after changing the voice port config, do a "shut" / "no shut" on the voice port to apply the change and run some test calls to see if it improves. If NOT, lower the output attenuation 1 db at a time and continue to run test calls until the volume is audible.

Hope this helps....
