ATA186 in SIP mode

I have an ata-186 and I was wondering if someone

already done this.

My ATA call the Cisco 1750 with FXS interface but

the 1750 doesn't call the ATA.

Re: ATA186 in SIP mode

I support the ATA and the 1750 and it would take more info to figure this out. It can be done and it will work. But we would need to see the show run and capture debugs as well as look at the ATA config. If you can open a case so someone can capture that info.

Re: ATA186 in SIP mode


Can you help to solve problem with ATA186 ?

It's strange we are running latest software, but unable to place 2 calls simoulteniously from the ATA186, even Codec is 0, Rec/Trans also equals 0.

Any suggestions ? ATA186 is registered with Cisco 3640 Gatekeeper and after that call is being terminated through AS5300. All codecs, like G723r53

are included in config on AS5300 side ...
