I'm trying to setup a 2811 with 3 E1/PRI ports using
currently running with IOS 12.4(15)T9, CME 4.1 and CUE 3.2.2.
I'd need to handle about 10 voice, ISDN, and analog connections each concurrently and transcode about 8 voice and 2 FAX calls to SIP and T38 concurrently.
I face several problems with this setup right now:
- The DSPs are obviously not enough to terminate 3 PRI connections, but the combined 90 timeslots won't be used all at the same time. Is there any possibility to configure the controllers to share the available DSP ressources so the device can handle all three PRI connections?
- From what I read so far I can combine Voice and ISDN dial-up with this setup but would need PVDM2-xxDM modules to also support analog dial-up. Is this correct or is there a possibility to use the installed PVDM2s to also provide analog dial-up?
- In case I have to mix PVDM2-xx and PVDM2-xxDM to accomplish my goal, what would be the best solution to add those? As the 2811 only features two DSP slots I'd have to add further DSP slots, would a NM-DSP-FARM module work?
