3745 ISDN PRI Connection to Siemens HiCom 300E

Dear All,

I am connecting Cisco 3745 VWIC-MFT2E1 to Siemens Hicom 300E DIUS 2 module (2 E1). The setup are:

FXS/FXO---Cisco 2651---(MPLS)----Cisco 3745---(E1)Siemens Hicom 300E---handset/PSTN

I follow the setup in cisco web page using ISDN PRI (isdn switch primary-net5, I tried QSIG before, but it work only half direction). It work well both direction, with one exception: The FXS from 2651 can not dial to PSTN trunk of Siemens Hicom 300 E. To get access to PSTN the user dial 0, but I can't get that line available for VoIP user.

Debug message shows that the error is 88 (incopatible destination).

Following is the config:

jkt-3745-mpls-v#sh run

I fthey are dialing 0 from the 2651 then there is no pots dial peer on the 3745 that matches 0. Add another dial peer just like 500 pots with a destination apttern of 0T and this should get through.

Hope this helps

Thanks for your response,

Sorry for incomplete information.

PBX users use 0 to dial to local PSTN. Now I connect the PBX to 3745 that is then connected to 2651 at another cities (this is still in the staging at the moment). The FXS users in the 2651 will dial 21412 for example to reach extension #412 and will dial 2107876543 to reach PSTN number 7876543 (there is preceeding 0 passed by the router to reach outside PSTN).

I think the dial-peer pots 500 with destination-pattern 21T match these two purposes, don't they ?

The problem now is that that '0' dial to reach outside PSTN is not working.

thanks,

.ari

OK...so you mean that for the PBX users dialing 0 to reach the PST no longer works, is that right?

If so, I would guess that the PBX is routing the call to the PRI where the 3745 is connected. Do a debug isdn q931 on the 3745 and have on of the PBX users dial 0 to confirm you see the call setup here. If so, then the PBX programming needs to be changed so that this PRI and the PSTN connection are 2 different routes.

Thanks Crieman,

There's call setup from 3745 and the PABX guy is working on it at the moment.

BTW I got quite strange problem. I have connected one remote site (the 2651 with fxs/fxo) and they can call back and forth to the PABX users in central location. When I connected the second site with similar configuration, it work with one exception that the the remote users (FXS behind second 2651) can't connect to PABX users (while pbx users can call the FXS). I did debug voice call setup and found error message with call disconnect with cause code 65.

Attached is the config of the second remote site (that's working in the first remote site) :
