SIP to SIP gateway

[mushechka]

Hello everybody

I want to ask about SIP to SIP gateway, is it realized by Cisco, or it's planed but not yet realized.

Thanx for your answer.

You can use a SIP Proxy, like Cisco SIP Proxy, or Vovida.org (Cisco Sponsored) Open-Source SIP Proxy.

If you want to implement it on a Cisco IOS device, it's not currently supproted on AS5xxx series, but it's on 2xxx and 3xxx series. It doesn't act as a SIP Proxy but as a back-to-back user agent. Search for the keyword IPIPGW on cisco.com, and AFAIK, it only works for H.323-H.323 and SIP-H.323, not SIP-SIP.

Hi, I did it using a back to back IPIPGW, How?...

SIP to H323 -> H323 to SIP

It's not the best option, but it works.

Why don't forget about Cisco and use a cheap, reliable and excellent documented products like Asterisk and SIP Express Proxy (SER). Both of them are GPL products, they just need a Linux server, work perfectly and have a lot of features.

Hi Every body,

I need your help to solve my problem if you met and fixed it.

I have a IPIP-GW runing for SIP to H323 call, the problem that there was some calls (SIP connection only) keep active status even if it disconnected in fact.
