Voicemail

[gustavocardozo]

I have a Cisco 3845 and Cisco 2811 used for telephony in to different sites connected through ipsec-isakmp.  All working well, i can call between sites ande receive external calls. The problen is with the voicemail, wen i call from site 1 to site 2 and no one answer the voicemail works, but from site 2 to site 1 if no one answer after 3 rings a get busy tone. When i call to any site from outside the voicemail works.

¿what can be wrong?

You could check the codec negotiated for that failed instance to see whether its a codec issue when transitioning the phone call to voicemail since calls from outside works fine.

Check the codec negotiated for the initial call and pls provide debugs to confirm the exact cause.

Sorry for the delay. ¿How can i get a debug from the call?

I check de codec configuration in both routers:

Please post full configs, this will let us know what protocols you are using and how your dialpeers are configured so that we can provide next steps.

I found the problem. The dspfarm profile in one site has de shutdown parameter. I took out that and the voicemail start working.

Thanks for all the assistance.
