As far as I know, with the introduction of the 12.2(8) IOS the 2600 series now can provide SIP services. My question is would this network topology function nad has anyone actually tried it. I am trying together a end-to-end SIP solution that interacts with the PSTN.
A 2650 using a 10/100 and digital t-1 modules. The T-1 is connected to ISDN PRI and the 10/00 would be routing to another 2650. Also, using a SIP proxy server and ATA-186. The call flow, abriged version, would go something like this.
A person using a Analog Phone places call. It is connected to the ATA-186. The signaling goes to the SIP proxy server. Proxy informs the ATA-186 to route packets to the LAN 2650 and also uses the DSP to packet the analog voice signal. The RTP packets are routed to the first 2650 using the 12.2.(8) running SIP. then the LAN 2650 routes the packets to the second 2560 which is set-up as a digital gateway connected to the PSTN. Then the two end users are now connected passing voice traffic via SIP, RTP and the traditional phone network.
I am somewhat new at network desgin for VOIP but does anyone beleive this would work and if not have I left anything out.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
