Hi,

I´ve a gateway 3825 with one E1 PRI (30 channels), and I need to route this 30 incoming calls to 2x VG224. First I´ve tried using CME on gateway and huntgroups, but on vg224 voice ports there are modem connected from some Bosch boxes, and there was an incompatibility with the codec when you use SCCP (g711ulaw) to control that voiceports, so I´ve tried using H.323 and g711alaw and it worked, but partially. I´ve this config:

voice call send-alert
voice rtp send-recv
!
voice service voip
fax protocol pass-through g711alaw
h323
modem passthrough nse codec g711alaw

voice class h323 1
  h225 timeout tcp establish 3

dial-peer voice 200 pots
incoming called-number 297922..
direct-inward-dial
port 0/0/1:15

dial-peer voice 2200 voip
preference 3
destination-pattern 29792200
voice-class h323 1
session target ipv4:<VG224_01>
codec g711alaw
no vad

dial-peer voice 2201 voip
preference 6
destination-pattern 29792200
voice-class h323 1
session target ipv4:<VG224_02>
codec g711alaw
no vad

I can place correctly the first 24 calls on vg224_01, but call # 25 is not placed on VG224_02. The gateway tries to place that call on VG224_01, and the call is lost.

There is a way that VG224_01 responds that has no more voice-ports available and then gateway place that call on VG224_02 ?

If the issue was outgoing calls, the solution will be trunkgroup an dial-peer pots, but for incoming calls I dont find a config to do this.

Any suggestion would be helpful.
