I have a problem to call from fxs port (2851, H323) to PSTN (E1) or to voip.

Phone connected to FXS port 0/1/1

I can call to 7-digit numbers, but there are 2 couples of call legs for 1 call:

(9 and 225 are pots dialpeer)

Rtr#sh voice call status

CallID CID ccVdb Port DSP/Ch Called # Codec Dial-peers

0x105F1 57A 0x470A7D28 0/1/1 0/3:1 91234567 g711ulaw 225/9

0x105F4 57A 0x4762C298 0/0/0:15.3 0/3:5 *91234567 g711ulaw 9/225

Q1. Is it normal?

Q2. i have dialpeer for long distance calls. i can make call by csim start <Long distance number>

Router shows it in sh dialplan number <Long distance number>, but don't show it in sh dialplan incall 0/1/1 number <Long distance number>

When phone place call, router selects incorrect dial-peer

Who can explain why? :-)

Q1: Yes it is normal. This is sometime called an "hairpinned" call, in which both DP's are POTS.

Q2: Please send DPs configuration explaining the how numbering works in your country, or just name the country you are in.
