Is anyone using a cisco router as an ISDN gateway with Asterisk? As you might have seen from a couple of my threads, I have been looking at Fritz! and Cologne cards, both of which require development against a specific version of asterisk/zaptel (e.g. chan_capi), which is intrusdive and causes a lag in deployment. I was thinking a better approach might be to use a seperate gateway, such as a Cisco 1751 with VIC-2BRI-NT/TE talking SIP to Asterisk, much like like an SPA3K in the analogue world. Any success stories? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20080218/34c401c3/attachment.htm
There has been some success using the 3810 series routers with a SIP image as an up to 6 port gateway. One fellow has even been able to come out of the 3810 T1 port into a channel bank and derive up to 30 channels, 24 from the T1 and 6 from the AVM with daughter boards. No extensive testing has been done regarding how many simultaneous channels can be up at one time, but that was not the intended use This even works with the minimal 3810 equipped with 8 Meg Flash and 32 Meg Ram John Novack Razza wrote:> Is anyone using a cisco router as an ISDN gateway with Asterisk? > As you might have seen from a couple of my threads, I have been > looking at Fritz! and Cologne cards, both of which require > development against a specific version of asterisk/zaptel (e.g. > chan_capi), which is intrusdive and causes a lag in deployment. > I was thinking a better approach might be to use a seperate gateway, > such as a Cisco 1751 with VIC-2BRI-NT/TE talking SIP to Asterisk, much > like like an SPA3K in the analogue world. > Any success stories? > ------------------------------------------------------------------------ > > _______________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > > asterisk-users mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users-- Dog is my co-pilot

I have no experience with BRI, but it should work as long as you have DSP cards for voice processing (the BRI card can do only data calls, and DSPs are needed for voice). __Yehavi:
We use PRI, not BRI, with Cisco gateways and it works great. Rock solid.

You shouldn't have any problem running Cisco routers for this (although I haven't used BRI for voice, I'm sure it'll work equally well). Just make sure you have the dsp's necessary installed for the simultaneous calls on the router you're planning to use. Regards, Tuukka
