Router 3825

[botelho.rocha1]

Hi,

I replaced my router 3845 to 3825 on my Network and I´m find a big problem about the config of interface integrated-Engine X/X on this one.

This configuration is very important because I want use this router to operate like PABX

Any help about this...??

Best Regards

Yha.

But this Router don´t want be my friend because same telephone models are not running.

like Cisco 7937

Cisco 7931

and

Cisco 6921.

Any ideia?

when you say that do you mean the phones wont run is it power up on poe?

Certain platform's only support certain types of poe.

Q. What IP phone models support the IEEE standard method of powered device detection?

A. These Cisco IP phones support IEEE 802.3af PoE:

• 7961G-GE

• 7971G-GE

• 7931G

• 7941G-GE

• 7945G

• 7965G

• 7975G

Note: These Cisco IP phones support both the Cisco pre-standard PoE and IEEE 802.3af PoE:

• 7970G

• 7961G

• 7906G

• 7941G

• 7911G

• 7962G

The phones are PoE but 7931, 7937 and 6921 are not working.

There is a way to add this models?

Meybe with license... or samething like that

If you give it a power block and it works fine then the issue is with poe , Unfortunatly no way to change the poe type its what the port is hardwired for , they changed poe recently on Cisco devices to become the standard rather than there own version. Example the new 3850 switches dont support 7940 phones either

[botelho.rocha1]

The phones do not register. They connect which means that PoE is running but not register on the network

[Mark Malone]

can you reach the call manager from the router , Unfortunatly im trained in voice so I may not be any help with the config side

This link has some good points about registration though for phones
