SIP early media 183 (SDP)

[SAToronto]

I am having an issue with some sip trunks. The vendor seems to feel its an issue with the pbx
I have 5 ip 500s all config'd identical. Same ARS...same shortcodes same trunk config.
On this particular PBX I can make a long distance call via my sip trunks with out any issues. When we try to make a local or a toll free call, the call goes out...shows as connected, but I cant hear them and they cant here me. The vendors replied with::: The toll free call has early media 183(SDP) but it looks like they don’t know what to do with it. Ask if they can support early media?. My opinion I think would be that if I can make a good long distance call on the trunks I should be able to make a local or toll free also. they are trying to say its an issue with my ARS. My ARS doesnt care what type of call it is..all calls go out the same way.

Does anyone have any ideas about this or ever had an issue like this??

Thanks

Wayne

I am not sure but could this help?

· Codec Lockdown: Default = Off.
Supports RFC 3264 Section 10.2 when RE-Invite Supported is enabled. In response to a SIP offer with a list of codecs supported, some SIP user agents supply a SDP answer that also lists multiple codecs. This means that the user agent may switch to any of those codecs during the session without further negotiation. The system does not support multiple concurrent codecs for a session, so loss of speech path will occur if the codec is changed during the session. If codec lockdown is enabled, when the system receives an SDP answer with more than one codec from the list of offered codecs, it sends an extra re-INVITE using just a single codec from the list and resubmits a new SDP offer with just the single chosen codec.


BAZINGA!

I'm not insane, my mother had me tested!

Thanks TLpeter
That did indeed work!!
I find it pretty sad that there are so many very qualified avaya guys on this site, but NONE in Toronto....Another issue that our interconnect couldnt resolve
