SRST issue

Unanswered Question
Jun 18th, 2008

1. Call Manager Version: 6.0.1

2. SRST router: Cisco 3825

3. Router IOS version: 12.4 (15) T5

4. IP phones:

• CP-7940G firmware version 8.0(5.0)

• CP-7960G firmware version 8.0(5.0)

After configured the SRST:

The IP phones 7940 & 7960 are configured with two line, line 1 for CUG codec G729 and line 2 for PSTN calling codec G711.At the time of failover phones are getting registered to the SRST router and 'CCM fallback mode' is being displayed on the phones. But there is no dial tone on the phone or if we press the speaker key it glows and goes OFF immediately. At the same time the memory utilization on the router is 80% to 90%.

Regards,

Raju

Hi Guys,

I got the same problem with my SRST, I tried to reconfigured it but there was no luck... is there a possibility that this could be a bug or something? do we have any resolution on this? Hope there is someone who can assist.

Many Thanks,

Dennis
