Hi, I've a got a Cisco 2610 with ISDN 10 PRI service, and a Cisco 1603 with ISDN BRI service. I dial out from 2610 to 1603. It is very weired that when the 1603 is in another state, (which means I need to put area code when I dial), I can ping from WAN interface of 2610 to WAN interface of 1603. Howerver, if the 1603 is in the same state of 2610, I cannot ping from WAN interface of 2610 to 1603. In both cases, I can see the call is established when I do a "show isdn active". The only difference I could see is: When 1603 is in another state, I can see from 1603 that the call is connected to 0312345678, which is the ISDN
10 number. However, when 1603 is in the same state of 2610. it says the call is connected to unknown. Is this the problem?Please help. Thank you very much.
