B179 with QSIG H323 Trunk - 503 Service Unvailable

[andri211]

I can dial and talk to other system using 1600 phone but I can't dial using B179

it show 503 service unavailable in monitor and the TO is 305@ip.ipo
the 305 extension is in other system, i supposed to have TO : 305@ip.othersys, right ?

have try change codec , change the shortcode using 3N"@ip.othersys"
have try dial from b179 using 305@ip.othersys

the incoming is working fine , the problem only in the outgoing call
any other suggestion perhaps ?

forgot to mention
b179 can talk internally and the other system is panasonic

You are overthinking it by looking at the SIP session data, it's more basic than that, like a shortcode/call routing/DMP issue. Look at it from that perspective and you will find the issue I reckon

its an ip trunk and i know no need to add @ip.other , tryin to thinking out of the box

shortcode : 3N dial 3N line:10
already check and uncheck DMP

its a shortcode problem ?

Your title says H323, but the discussion has centered around SIP. Call setup is very different between the two. Do you have SIP between the two sites, or H.323?

 

[andri211]

the trunk between site is H323 but b179 is SIP

Do a default monitor trace when making a call from the B179, that should say what's wrong. Might need one from the other end as well.
