Add Cell Phone to Cisco ISR 2911

[Marcel Belisle]

I would like to know if it is possible for me to get an interface for my ISR router that would allow me to connect a cell phone. Reason been I would like to make some configuration to route my VoIP users through a cell phone whenever they are making calls to a Cellular phone. 

I have a Cisco 2911 and also running CUCM 10.5 server. Please help.

Hi.

I don't think it's possible but there are many GSM gateway event with low price to achieve this.

would you know if this exist as a network module that can be added on to a Cisco router or is it a separate appliance.

Hi.

Unfortunately no gsm modue for voice is available, data only.

There are a lot of gsm gateway which can talk SIP or H323 with CUCM/CUCME and they are external boxes.

If it is least cost call routing you are after, you will need to deploy a GSM gateway,  which is configured as a SIP trunk from a CUCM point of view.  it contains a bunch of SIM cards and has an external antenna, these guys make it:  http://www.topex.ro/
