SRST - Why does call forward require a #

Have a situation when router falls into SRST, all calls are working fine, but we notice that Call Forward will time out if you don't include a # at the end of the dial string.

By the way, we're talking call forward initiated at the phone, not configuration in IOS.

Meanwhile, if the phone dials the same number no # is required, which makes me think it's not a dial-peer problem, or at least not a problem with matching a destination pattern.

Does anyone know what might be causing this or know of a solution so that # does not have to be entered. Apart from manually configuring call forward in the router.

Thanks in advance.


Re: SRST - Why does call forward require a #

Well it is definatly a dial-peer issue. There is a call-forward pattern under the srst config, maybe that pattern is targeting things with a # at the end specifically. Something like .T# if it is, just change it to .T ;) . Also paste the running config!

HTH, please rate useful posts.

Re: SRST - Why does call forward require a #

Okay... what follows is what I consider possibly relevant portions of the config.

IP's have been excluded, and any real phone number changed to some version of 111222XXXX.

I notice under fallback "transfer-pattern .T blind". Chad mentioned changing .T, but what does the blind component do?

Secondly, I see a second pattern of 10 dots. I suspect this is the real culprit. Anything less than 10 digits is likely getting an interdigit timeout because of this.

Re: SRST - Why does call forward require a #

looking at this I still say it should be call-forward pattern .T but I don't see how this would fix your problem :)..

Re: SRST - Why does call forward require a #

I think there is a call forward pattern command you need to add specifically to each ephone. just like the one you have in call-manager-fallback.

Re: SRST - Why does call forward require a #

Oh man, I hope that's not the case. I have an attempt to fix in place. If testing still has the problem, then I'll try this.

Re: SRST - Why does call forward require a #

Yeah, that's I'm trying now. I made the following changes yesterday before reading this.


no transfer pattern ..........

no call-forward pattern ..........

call-forward pattern .T

I'm having the end users test call forwarding to internal numbers and external numbers (internal just happen to have a 10 digit dialplan (yuck)), so I should know soon whether or not they still need a # to complete the string.
