These error messages could be due to one of these Cisco bug IDs:
- CSCed67369: 2600xm guido_port_dsp_connect: vic connect failed and SegV crash.
- CSCeh59299: guido_port_dsp_connect: vic connect failed messages displayed.
- CSCef67454: dsprm reports error after repeated shut/no shut on trunk.
For example, this represents a voice port that is trunked to a multicast address. Repeated shut or no shut reproduces the reported issue. The 3/0/1 g711ulaw y S_CONNECT S_TRUNKED dsp error messages show in the logs:
TDM: guido_port_dsp_connect: vic connect failed flex_dsprm_voice_connect: voice tdm connect failed
A subsequent shut/no shut does not recover the port.
To overcome the problem documented in Cisco bug ID CSCed67369, upgrade the Cisco IOS version to either 12.3(8.3)T or 12.3(11)T.
To overcome the problem documented in Cisco bug ID CSCeh59299, perform one of these workarounds:
- Reset the Cisco IOS gateway.
- Add the no local-bypass global command to the router configuration as shown:
voice-port 1/0/0 timeout wait-release 2< timeout call-disconnect 2 shut no shut voice-card 1 no local-bypass
If these procedures are not successful, upgrade or downgrade the Cisco IOS version to either 12.3(11)T7 or 12.3(11)T8.
To overcome the problem documented in Cisco bug ID CSCef67454, power cycle the router.
If this does not solve the problem, upgrade the Cisco IOS version to 12.3(11.5)T or later or to 12.3(12.12)T1 or later.
Use the latest 12.3(14)T version available or the latest 12.4 mainline Cisco IOS version available (12.3T became 12.4 mainline).
To download the above appropriate Cisco IOS versions, refer to Software Center (Downloads): Cisco IOS Software.
