small IP Telephony solution

I am configuring a IP Telephony system for a little company that needs about 30 phones and a PRI E1 connection to the PSTN.

To keep the price as low as possible I would like to use mostly Cisco Ip Phones 7905 (15 units), 7910 (12 units) and ATA (10 units) to reuse existing DECT/GAP mobile phones. For the same reason I would like to use a SRST solution based on Cisco2600XM.

Could you please confirm me that this solution is suitable for the required number of phones, and give me the code of the E1 interface I have to install in the router and the code of the license to activate SRST on the router?

Re: small IP Telephony solution

You CANNOT use SRST as a call manager for any install. SRST is ONLY for disaster recovery at remote sites when call manager is not available. The phones must register with call manager before failing over to SRST. If you want a small office solution, take a look at IOS Telephony Services, but my understanding is it won't be available until summer, but talk to your local CAM.

Otherwise you will have to use a call manager setup, check out the ICS 7750.

Re: small IP Telephony solution

Thank you for your support.

Because I don't find IOS Telephony Services on the price list, I suppose it continues to be named SRST. Is it not true??

I believe it was already available...

Re: small IP Telephony solution

IOS Telephony Service is currently available and a very viable alternative for smaller offices.

I recommend running at least 12.2(11)T and you have to pay for the feature license.

IOS telephony service is available now. See:

and see your account manager for licensing, its not free.
