Voice Gateway

[Raminkn20]

Hi. I have a Cisco ISR921 router. Can I use it as a voice gateway to establish sip trunk connection with SBC?

I don't have voice commands on that and I can't see UCK9 license on that.

Hello @Raminkn20 

isr921 cannot be used as a voice Gw or CUBE because it lacks DSP resources... voice features and ucK9 licensing !!! It is designed/used only for routing and branch conectivity.

Do you have any suggestion to use as a voice gateway for small business?

ISR 4000 series are end of sale and I can't find an appropriate one.

Hello @Raminkn20 

See series catalyst 8200/8200L.

These are newer routers that many are using as sucessors to the older ISR and voice gateway platforms.
