No Voice over outbound SIP

[trupeni2012]

Setup

phones---------CUCM------------CME---------ASA------Internet----------SIP Provider

We have an issue where outbound calls through our sip, signaling completes but we dont get audio. In the other direction Inbound sip calls work fine.

From the traces i have taken on an inbound and outbound calls on CME and ASA i dont see any difference and all looks to be fine.

This problem happened when we relocated office and had to change the CME ip address and the addition of an ASA fw. The ASA is setup to inspect SIP.

Hi there,

Can you clarify if you're saying that the call setup completes and you're on the line with the other person, but they can't hear you? And if so, can you hear them?

Can you share the CME and ASA configuration? The two things I'd look for to start is

1. That the right codec was negotiated
2. ASA isn't blocking/dropping any traffic

Regards,

Tim
