VOIP gatekeeper problem.

Unanswered Question
Apr 7th, 2008

I have a PRI card connected to a PBX. Am able to make outgoing calls from internal extensions but external calls are not being forwarded through the PRI card. The setup has been OK till last week.This is the config on the card:

interface Serial0/3/0:15

no ip address

isdn switch-type primary-net5

isdn not-end-to-end 64

isdn protocol-emulate network

isdn incoming-voice voice

isdn send-alerting

no cdp enable

This is one my dial peers:

dial-peer voice 3000 pots

destination-pattern 41....

progress_ind setup enable 3

direct-inward-dial

port 0/3/0:15

forward-digits 4

I have this problem too.

check using the following

show isdn status

Place a call and do a

debug isdn q931

For the config you have we are only able to send 4 digits to other side

....

Let us know above outputs

Dear all,

Please add "isdn sending-complete" on ISDN interface, & add "incoming called-number ." on dial-peer.

thanks

Hi,

Find the output on the gatekeeper based on the above:

VOIP#show isdn status

Global ISDN Switchtype = primary-net5

ISDN Serial0/3/0:15 interface

******* Network side configuration *******

dsl 0, interface ISDN Switchtype = primary-net5

Layer 1 Status:

ACTIVE

Layer 2 Status:

TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED

Layer 3 Status:

2 Active Layer 3 Call(s)

CCB:callid=219, sapi=0, ces=0, B-chan=21, calltype=VOICE

CCB:callid=21A, sapi=0, ces=0, B-chan=20, calltype=VOICE

Active dsl 0 CCBs = 2

The Free Channel Mask: 0xFFE77FFF

Number of L2 Discards = 0, L2 Session ID = 5

Total Allocated ISDN CCBs = 2

VOIP#

19:38:47: ISDN Se0/3/0:15 Q931: Applying typeplan for sw-type 0x12 is 0x0 0x0, Called num 3318

19:38:47: ISDN Se0/3/0:15 Q931: TX -> SETUP pd = 8 callref = 0x060A

Bearer Capability i = 0x8090A3

Standard = CCITT

Transfer Capability = Speech

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Channel ID i = 0xA98381

Exclusive, Channel 1

Progress Ind i = 0x8183 - Origination address is non-ISDN

Called Party Number i = 0x80, '3318'

Plan:Unknown, Type:Unknown

19:38:47: ISDN Se0/3/0:15 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x860A

Cause i = 0x81A9 - Temporary failure.

This is an example of a call made to this gatekeeper from one of the gateways to an extension at a remote site:

030R#csim start 413318

csim: called number = 413318, loop count = 1 ping count = 0

csim err csimDisconnected recvd DISC cid(12232)

csim: loop = 1, failed = 1

csim: call attempted = 1, setup failed = 1, tone failed = 0

Same problem persists.

Hi,

The problem was resolved by resetting the card on the PABX,

CAll are going on well now,

Thanks for your advice though.
