I have two routers connected together via a T1 Crossover cable in my lab. I can make calls one way fine, ie I can call from ext. 2001 to ext. 7000 with no problem. However when I call from ext 7000 to 2001 I see the call go through on my traces however on the calling end I hear dialtone. On my q931 trace I notice one router is sending a Connect message instead of an alerting message. Here is the trace
00:27:41: ISDN Se1/0:23 Q931: RX <- SETUP pd = 8 callref = 0x0005
Bearer Capability i = 0x8090A2
Standard = CCITT
Transer Capability = Speech
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA98381
Exclusive, Channel 1
Calling Party Number i = 0x0081, '7038758000'

Called Party Number i = 0x80, '2001'

00:27:41: ISDN Se1/0:23 Q931: TX -> CONNECT pd = 8 callref = 0x8005
00:27:41: ISDN Se1/0:23 Q931: RX <- CONNECT_ACK pd = 8 callref = 0x0005
00:27:44: ISDN Se1/0:23 Q931: RX <- DISCONNECT pd = 8 callref = 0x0005
Cause i = 0x8290 - Normal call clearing
00:27:44: ISDN Se1/0:23 Q931: TX -> RELEASE pd = 8 callref = 0x8005
00:27:44: ISDN Se1/0:23 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x0005

Any Ideas what would cause the calls not to work one way..
Thanks
