The ios router does not need DSP's to convert 2833 to sip-notify. IOS router does need DSP's for inband dtmf i.e. within the audio stream ( do not get confused by 2833 which is also in band) to sip-notify. All you need to make your case work is incoming dial peer with 2833 and the outgoing dial peer with sip-notify you should be good to go. If it doesnt work attach deb ccsip messages deb voip ccapi inout and deb voip rtp session named-event all in one file.
Sorry for late reply. I was on a field trip and couldn't access the web.
Thanks auppal & ADAM CRISP and I have learnt valuable points from your reply.
I have gone through all the comments and thanks for your valuable comments. The voice mail server seems to be connected with the SIP proxy using the proprietary method of access and den;t dial out any number. Hence the solution I have initially proposed seems to be irrelevant.
Since the setup is seems to be complex because of the nature of the voice mail server i'm trying to go for another type of soluton as below
1. ATA(RFC2833)------ --internet----->SIPproxy------->VoicemailServer 2. ATA(RFC2833)------ --internet----->SIPproxy------->3845router(Inband)---- --->3rdPartyCarri ers
earlier I have placed the router in between SIP proxy and VoicemailServer. Now decided to use the RC2833 at the ATA side so that voice mail server directly understand it and need to conver to inband before reaching the 3rd party carriers since most of them support only inband.
Hence the voice mail server issue sorted I need your help on configuring the router for all the carriers.
Can you please suggest any best solution to configure the router in shorter way rather than having dial peer profile for each carrier.
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...
