887 ISR with 7960 IP Phone

toshi-esumi · ‎10-07-2011

Hi,

We currently installing 877 with 7960 phones to our customers. Since 877 is end of life, I'm testing 887 to replace it. However, the 887(CISCO877-SEC-K9) we bought to test came with c880data-universalk9-mz.150-1.M6.bin.We bought this product since we use BGP for routing (Advanced IP is required). And that seems to the reason "switchport voice vlan 2" to let 7960 to learn voice VLAN and feed some infomation via DHCP. The config works with 877s.

Is it possible for me to upgrade the IOS to c880voice-.... with 887 to make this work? Or is it only for 88x SRST hardware?

Thanks,

Toshi

Sorry for poor English. I obviously meant the IOS revision seemed to be the reason that the IP phone doesn't work.

Only for the 88x SRST hardware. Can you please try one of the later IOS images

Thanks

I upgraded the IOS to c880data-universalk9-mz.151-4.M2.bin, which seems to be the latest M version. But a 7960 doesn't take vlan 2 as the operational vlan. Is it supposed to be supported?

Will I have the same issue if I use 7960G IP Phone? If so, what is the difference between 7960 and the G version?

Thanks,

We found the cause of the problem ourselves. CDP was not running with default config. After we did "cdp run", it started working.

Thanks,
