IP Phone shows only 1st digit of called number if overlap-signal enabled, Open CSCtw62055

Symptom: A Cisco IP Phone registered to a Cisco Communications Manager Express (CME) system will show the called number on its LCD screen as a single digit (typically the first digit of the called number on the PSTN), after receiving alerting from the PSTN, instead of the complete called/dialed number.
Conditions: Observed on a CME 8.8 system (IOS 152-1T or higher) that has the following command enabled for sending overlap digits to a BRI or a PRI link on the PSTN side: ! telephony-service overlap-signal ! command guide for reference: http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/command/reference/cme_o1ht.html#wp1028436
Workaround: Disable "overlap-signal" if feasible and send the called digits en-bloc (like a regular ISDN call).

SRST8.0: 7937, 79x1/5/2 with sccp version 17 would not register to SRST, Fixed CSCte08121

Symptoms: Cisco IP phones running firmware that uses SCCP version 17 cannot register to SRST/CME-SRST, or will register but not obtain any lines.
Conditions: This symptom is observed on Cisco routers with Survivable Remote Site Telephony (SRST) and Cisco IOS Release 15.0(1)XA. This is the first image with SCCP version 17 support for SRST.
Workaround: Download the IP phone firmware to a Cisco IOS release image that does not use SCCP version 17. For Cisco 79x1/5/2 phones and Cisco 797x phones, this is 8.3 firmware. For Cisco 7937 phones, obtain a load prior to 1.4(1).

Conditions: This symptom occurs when calls to the SCCP SNR phone and SNR call-forward noan timer (cfwd-noan) are configured. Both SNR and mobile phones do not answer the call and the call is forwarded to voice mail.
Workaround: There is no workaround.

Conditions: The problem is triggered when there is no dsmp resource for making a call and the phone goes on-hook in a second. If the agent doesn't go on-hook, the problem may be avoided.
Workaround: Remove the stuck ephone-dn. Create a new ephone-dn with the same directory number and assign it to the phone Reload of the router also will clear the problem.
