vg200 isdn bri problem

dear all,

I have [IPPhone] - [CCM] - (voip FastEthernet) - [VG200 as H323 GW] - (pots ISDN/BRI VIC) - [PSTN] configuration, and I make dial-peers inside VG200 like below:

--

dial-peer voice 3 pots

answer-address 0

direct-inward-dial

prefix 00

!

dial-peer voice 4 voip

destination-pattern 00

session target ipv4:[MyIPPhoneIPAddr]

!

dial-peer voice 5 voip

answer-address [MyIPPhoneDN]

!

dial-peer voice 6 pots

destination-pattern 22T

port 1/0/0

--

from the debug information (isdn q931, cch323 h225, voip ccapi inout), I can see that :

1) both legs (voip and pots) are matched when calling from IPPhone to PSTN, but outbound call from VG200 is failed (Cause i = 0x82E46C - Invalid information element contents).

2) only pots leg is matched when calling from PSTN to IPPhone (Cause i = 0x8081 - Unallocated/unassigned number), I think this because no more peer match to make outbound call (ssaCallSetupInd cid(3), st(SSA_CS_CALL_SETTING),oldst(0),ev(24)dpMatchPeersMoreArg result= -1)

- I dont understand th reason of 1) disconnect.

- 2) disconnect shouldnt be happened because it already match peer #3 (cc_api_call_setup_ind vdbPtr=0x811B809C,callInfo=called=,called_oct3=0x81,calling=0948260968,calling_oct3=0x0,calling_oct3a=0x83,calling_xlated=false,subscriber_type_str=RegularLine,fdest=1,peer_tag=3, prog_ind=0},callID=0x80E77590)), where prefix 00 then added to match peer #4 to do outbound call to IPPhone.

can anyone explain me? below is my necessary config infos:

Re: vg200 isdn bri problem

I wonder why the voice port has not been configured for the "dial peer 3". Could you check if this is causing the problem.

Check out the following document for more details.
