Hello!
There are two 1760, the first one has VWIC2-1MFT-T1/E1, the other VWIC2-2MFT-G703. They are directly connected by E1 crossover cable, to emulate connection between a cisco router and a PBX.
I've configured CCME on both routers, the first one (1760-First) having the extension range 1xxx for IP phones, the second (1760-Second) - 2xxx.
This is how I've configured routers.
------------------------------------
==== 1760-First ===
Phones have 1xxx range.
Only a part of config having realtion to voice is displayed.
isdn switch-type primary-qsig
controller E1 0/0
pri-group timeslots 1-4,16
interface Serial0/0:15

---------------------------------
However, when I attempt to make a call from 1001 to 2001 (or vice versa), the call doesn't proceed. I hear a signal, and after some time the calling phone drops the call. At the time, other phone displays no coming calls.
What is the most likely reason of the problem?.. Here is the debug output tkaen from 1760-Second:
*Mar 11 00:48:51.117: ISDN Se0/0:15 Q931: RX <- SETUP pd = 8 callref = 0x008B
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
Calling Party Number i = 0x0080, '1001'
Plan:Unknown, Type:Unknown
Called Party Number i = 0x80, '001'
Plan:Unknown, Type:Unknown
*Mar 11 00:48:51.165: ISDN Se0/0:15 Q931: TX -> CALL_PROC pd = 8 callref = 0x808B
Channel ID i = 0xA98381
Exclusive, Channel 1
*Mar 11 00:48:51.165: ISDN Se0/0:15 Q931: TX -> CONNECT pd = 8 callref = 0x808B
Connected Number i = 0x80, '001'
*Mar 11 00:48:51.185: ISDN Se0/0:15 Q931: RX <- CONNECT_ACK pd = 8 callref = 0x008B
*Mar 11 00:49:07.143: ISDN Se0/0:15 Q931: RX <- DISCONNECT pd = 8 callref = 0x008B
Cause i = 0x8290 - Normal call clearing
*Mar 11 00:49:07.155: ISDN Se0/0:15 Q931: TX -> RELEASE pd = 8 callref = 0x808B
*Mar 11 00:49:07.167: ISDN Se0/0:15 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x008B
I cannont understand why the first figure of the number 2001 is dropped?..
I'll be very grateful for ideas.

Dmitry

Hi,
This happens because POTS DP consumes the digits matched in destination-pattern.
So under dial-peer, configure "forward-digits all" or "no digit-strip".
You also need a pots DP with DID, like:
dial-peer voice 333 pots
incoming called-number ....
direct-inward-dial
Hope this helps, please rate post if it does!

Many thanks!
