Cisco 2821 with 4 E1 connected to PSTN. Most outgoing calls flow without any issues, but sometimes fails (debug isdn error shows "CCPMSG_OutCall: fails with cause 0x2C"). I see enough free timeslots in E1 at this time. This E1 using for outgoing calls only, incoming calls come via other E1.

Router configuration:

controller E1 0/1/1
framing NO-CRC4
pri-group timeslots 1-31

interface Serial0/1/1:15

no ip address
encapsulation hdlc
no logging event link-status
isdn switch-type primary-net5
isdn timer T303 120000
isdn incoming-voice voice
isdn map address .* plan isdn type national
isdn send-alerting
isdn negotiate-bchan resend-setup
isdn bchan-number-order ascending round-robin
isdn sending-complete
no isdn outgoing display-ie
trunk-group PSTN 10
no cdp enable
