Description:     I&ASTERISK-177;m trying to make work Asterisk against a Cisco IAD2431 with chan_mgcp. Since chan_mgcp assumes the Line package is the default which is not the usual with Cisco&ASTERISK-177;s GW I made a little patch which signals the package. Also the event "cg" is on Generic Media package so I changed "cg" to "G/cg". I can make and receive calls now and I think it shouldn&ASTERISK-177;t hurt others MGCP endpoints.
       There are other problems, for example Cisco don&ASTERISK-177;t like how Asterisk signals more than one codec, since a:PCMU;PCMA should be used instead of a:PCMU, a:PCMA. And chan_mgcp always uses ulaw as the default even if a use "allow" in mgcp.conf. I&ASTERISK-177;ll try to make GSM work and some  other stuff, like hook flash transfer and then send another patch since that could break interoperation with others mgcp GWs.

  Sorry to bug you. I forgot to mention this is a patch. I have another patch to handle request for wildcard endpoint and I&ASTERISK-177;ll like to see if this one could be applied to the code before sending more patches.

Could you please update to current CVS and ask for testing on the mailing list?

   Give some time, since my development box is offline. I had tested this with the Cisco IAD and an Oki with 2FXS + FXO backup and worked fine. I'll try to sync my code with the CVS this week. Also I added support for the * endpoint.

   I updated the patch against last CVS (03/30/2004) please test in order to send  another patch I have to add suport to * endpoint in RSIP messages. The file is cisco_iad_mgcp2.diff.gz.

   I want to continue to improve chan_mgcp but if nobody test this patch in order to get in CVS I cannot sync this stuff everytime head changes. Please test.

Sorry, haven't got any MGCP equipment to test with. I'll send a reminder to the -dev list.
