Although in case WAN is up when you call into from PSTN the call will be forwarded to Unity thru WAN but may be somehting weird at PSTN end. Jsut trying to do isolaton here.

When the WAN is up the DTMF digits are going fine and 3001 phone login to its voice mail box with PIN. But when is on AAR or SRST, the calls are connected to VM with correct mailbox but the DTMF digits are not going through. Which results 3001 is not able to login to VM with PIN. The same problem is seen between CME (E1 PRI) to AA on CUE over PSTN trunk. Sometimes the voice quality is very bad and unable to hear the unity announcement. But the DTMF is not working even when the voice quality is good. There is no path code or line code violations are in show controller output in BR1 and PSTN gw as well. Could someone tell me how to fix this.
