I encountered this linecode issue last week. Changing it to B8ZS fixed my problem.

It is set to "linecode ami" in the initial config, but should be "linecode b8zs".

Pretty straightforward stuff, except the calls never seem to get out of the PSTN router. When dialing the HQ phone from the PSTN phone (regardless of line selected), I get the following debug isdn q931 errors from the PSTN router: May 6 23:11:09.243: ISDN Se0/3/0:23 Q931: Applying typeplan for sw-type 0xD is 0x0 0x0, Calling num 911 May 6 23:11:09.243: ISDN Se0/3/0:23 **ERROR**: CCPMSG_OutCall: fails with cause 0x22 And every 30 seconds, I see the same batch of 4 ISDN Restart messages, like this (also from the PSTN router): May 6 23:12:04.539: ISDN Se0/3/0:23 Q931: TX -> RESTART pd = 8 callref = 0x0000 Restart Indicator i = 0x87 May 6 23:12:05.539: ISDN Se0/3/0:23 Q931: TX -> RESTART pd = 8 callref = 0x0000 Restart Indicator i = 0x87 May 6 23:12:06.539: ISDN Se0/3/0:23 Q931: TX -> RESTART pd = 8 callref = 0x0000 Restart Indicator i = 0x87 May 6 23:12:07.539: ISDN Se0/3/0:23 Q931: TX -> RESTART pd = 8 callref = 0x0000 Restart Indicator i = 0x87 Show isdn status on the PSTN router looks normal for this interface: ISDN Serial0/3/0:23 interface ******* Network side configuration ******* dsl 1, interface ISDN Switchtype = primary-ni Layer 1 Status: ACTIVE Layer 2 Status: TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED Layer 3 Status: 0 Active Layer 3 Call(s) Active dsl 1 CCBs = 0 The Free Channel Mask: 0x80000000 Number of L2 Discards = 0, L2 Session ID = 0 Attaching show run and show isdn status as well for the HQ router (the other end) just for troubleshooting completeness, but there's no indication of anything amiss, nor any debug messages at all, on the HQ router. The call never gets that far. I started this morning on Voice Pod 11 and hit this. Ryan was kind enough to move me over to Voice Pod 16, but I'm hitting the same issue here. OSL archive and Google search turned up nothing concrete, other than a general theme of "it sounds like your telco / carrier has issues." :) Any ideas? Cheers and TIA, sd
