G.711 30ms support on 2600

[aljaz]

Hi all!

I would like to find (working) IOS for VoIP connection with G.711 codec with 30ms packetization (payload 240B) on 2600 router with FXO NM. I tried with 12.2.6a, 12.2.XT, 12.1.5.T8. I would like to make IP phone call via 2600 to PBX subscriber. Ip telephone supports only 30ms packetization. I get ringing tone on normal phone, but when I answer to the phone I get a message that the payload is to big and connection clears.

Anyone have better experiances?

Best regards,

Tomaz

Did you configure the 30ms sample size on the 2600 voip dial-peer? If so, sounds like you need to add incoming called-number . to the dial-peer.

I will add incoming called-number, but just some more background; configuration works with 20ms (160B payload) only 30ms get's errors, also G.723 (6.3k) works without problem.

I keep you updated if your suggestion solve problem.

Best regards,
